[Bug 2167190] Re: [amdgpu][Navi 31] Reboot hangs on HWE 7.0; 6.17 works; blocking amdgpu avoids hang

Tested on Linux Mint 22.3 using Ubuntu-provided kernels. This has not yet been reproduced on an Ubuntu installation. ## Summary On Linux Mint 22.3 (Ubuntu 24.04 base), restarting with Ubuntu HWE kernel 7.0 can leave the screen off and fans running/ramping, requiring a power-button reset. Kernel 6.17.0-40 has restarted successfully with graphics enabled and is the current workaround. Normal power-off and restart directly from BIOS have also worked. The strongest comparison is between two text-mode boots of the same 7.0.0-31 kernel: reboot hung with Intel graphics blocked and AMDGPU initialized; reboot succeeded after additionally blocking AMDGPU. This strongly implicates the AMDGPU initialization/shutdown path or its interaction with other kernel components. It does not establish the exact defective function or commit. A malformed earlier blacklist test reportedly restarted with Intel still loaded, so intermittency remains possible. ## Environment - Linux Mint 22.3, Ubuntu noble base, x86_64. - Working installed kernel: 6.17.0-40-generic, package 6.17.0-40.40~24.04.1. - Failing kernel: 7.0.0-31-generic, package 7.0.0-31.31~24.04.1, upstream version reported as 7.0.14. - Also reported failing: 7.0.0-28 and 7.0.0-30. - Discrete GPU: AMD Navi 31, PCI ID 1002:744c, ASRock subsystem 1849:5308. PCI naming covers RX 7900 XT/XTX variants; exact retail model not established here. - Integrated GPU: Intel Alder Lake-S GT1, PCI ID 8086:4680, i915 driver under normal operation. - Motherboard: MSI PRO Z690-A WIFI (MS-7D25). - BIOS: A.D0, dated 2023-07-10. ## Tests and evidence | Test | Boot configuration | Reported result | | --- | --- | --- | | Installed 6.17.0-40 | Normal graphical boot | Reboot worked | | Mint live USB, 6.14.0-37 | Live desktop | Reboot worked | | 7.0.0-31 | Normal desktop | Reboot hung | | 7.0.0-31 | `systemd.unit=multi-user.target` | Reboot hung; LightDM did not start | | 7.0.0-31 | `systemd.unit=multi-user.target nomodeset` | Reboot worked | | Test B, 7.0.0-31 | `systemd.unit=multi-user.target module_blacklist=i915,xe` | Latest test hung | | Test C, 7.0.0-31 | `systemd.unit=multi-user.target module_blacklist=i915,xe,amdgpu` | Reboot worked | Test B on September 13 at 10:26 CDT recorded: ```text Module i915 is blacklisted Module xe is blacklisted [drm] Initialized amdgpu 3.64.0 for 0000:03:00.0 on minor 1 ``` Test C on September 13 at 10:33 CDT recorded: ```text Module i915 is blacklisted Module xe is blacklisted Module amdgpu is blacklisted ``` The preserved journal reaches the final systemd shutdown stage and stops when journald terminates. No preserved stack trace identifies the hang. Reaching reboot.target or seeing Journal stopped alone does not prove a reboot succeeded; success/failure outcomes above come from the user's physical observations. Earlier 7.0 boots logged AMD display REG_WAIT timeouts, but those messages alone do not establish the cause. A temporary EFI reset- method test also hung. Current measurements taken during normal operation did not show overheating; temperatures during the actual hang were not captured. ## Current workaround GRUB defaults to 6.17.0-40-generic with normal graphics drivers enabled. The kernel image and module packages are marked manually installed. Kernel updates remain enabled, but newly installed kernels will not automatically replace this explicit default. Local configuration: - `/etc/default/grub.d/99-working-kernel.cfg`: working default and five-second menu. - `/etc/grub.d/42_reboot_diagnostics`: optional tests A, B, C. Do not use the all-GPU blacklist or nomodeset as the normal daily boot configuration if GPU acceleration is required. ## Suggested maintainer follow-up Review as an AMDGPU-related regression between 6.17 and 7.0. Identify a relevant fixed distribution kernel or request targeted late-shutdown traces. Repeat the B/C comparison if needed because the failure may be intermittent. Further isolation should be based on maintainer guidance rather than changing unrelated BIOS settings or disabling broad power- management features. Related reports found during research involve other AMD hardware and do not establish that the same defect or fix applies here. No specific published fix was verified for this machine.

[Bug 2167202] [NEW] thunderbolt/pci JHL7440/AQC113 fails to recover after tunnel disconnect; BAR allocation fails

Public bug reported: A bus-powered JHL7440 Thunderbolt enclosure containing an AQC113 spontaneously disconnects on both USB4 ports.

[Bug 2167177] Re: Intermittent SPI keyboard/trackpad failure at boot — DMA/PIO module load order race in spi_pxa2xx_pci

** Tags added: kernel-daily-bug -- You received this bug notification because you are subscribed to linux in Ubuntu. Matching subscriptions: Bgg, Bmail, Nb https://bugs.launchpad.net/bugs/2167177 Title: Intermittent SPI keyboard/trackpad failure at boot — DMA/PIO module load order race in spi_pxa2xx_pci Status in linux package in Ubuntu: New Bug description: On a MacBook8,1 (2016 12" MacBook, Intel Broadwell), the internal SPI keyboard and trackpad intermittently fail to initialize at boot. A restart always resolves the issue. The failure is caused by a race between dw_dmac_pci and pxa2xx_spi_pci module probe order. Symptoms: Intermittent: keyboard and trackpad not detected after boot (no input: Apple SPI Keyboard / input: Apple SPI Touchpad in dmesg) Restart always fixes it No external keyboard required to reproduce (it's a boot-time race) Root Cause: The spi_pxa2xx_pci driver checks for DMA channel availability at probe time. The outcome depends on whether dw_dmac_pci has already registered its channels: Good boot: pxa2xx_spi_pci probes first → "no DMA channels available, using PIO" → works Bad boot: dw_dmac_pci probes first → SPI sees DMA → uses DMA → transfers time out (-110) → driver re-queues a message still linked in the SPI core's list → list corruption (__list_add_valid_or_report warning) → driver is permanently stuck Failed boot log (kernel 7.0.0-31-generic): dw_dmac_pci 0000:00:15.0: DesignWare DMA Controller, 8 channels input: Apple SPI Keyboard as /devices/pci0000:00/0000:00:15.4/spi_master/spi1/spi-APP000D:00/input/input4 applespi spi-APP000D:00: SPI transfer timed out applespi spi-APP000D:00: Error writing to device: -110 spi_master spi1: failed to transfer one message from queue applespi spi-APP000D:00: SPI transfer timed out applespi spi-APP000D:00: Error reading from device: -110 WARNING: lib/list_debug.c:35 at __list_add_valid_or_report+0xc6/0xe0, CPU#3: spi1/455 spi_queued_transfer+0xed/0x110 __spi_async+0xd5/0x160 spi_async+0xd6/0xe0 applespi_send_cmd_msg+0x17d/0x400 [applespi] applespi_msg_complete+0xc5/0x110 [applespi] applespi_async_read_complete+0x5c/0x60 [applespi] spi_master spi1: failed to transfer one message from queue applespi spi-APP000D:00: SPI transfer timed out applespi spi-APP000D:00: Error writing to device: -110 Successful boot log (same kernel, same machine): pxa2xx_spi_pci 0000:00:15.4: no DMA channels available, using PIO dw_dmac_pci 0000:00:15.0: DesignWare DMA Controller, 8 channels input: Apple SPI Keyboard as /devices/pci0000:00/0000:00:15.4/spi_master/spi1/spi-APP000D:00/input/input4 applespi spi-APP000D:00: Received corrupted packet (crc mismatch) applespi spi-APP000D:00: modeswitch done. input: Apple SPI Touchpad as /devices/pci0000:00/0000:00:15.4/spi_master/spi1/spi-APP000D:00/input/input5 Upstream Status: The list-corruption bug (re-queueing applespi->wr_m via spi_async() while still linked in SPI core lists) was identified in the sashiko- bot review of the v4/v5 patch series (Shih-Yuan Lee, July 2026, linux- spi mailing list).

[Bug 2167160] Re: [HawkPoint1 1002:1900] gfx_0.0.0 timeout, failed MES ring reset, then GNOME Shell SIGABRT and session loss

** Tags added: kernel-daily-bug -- You received this bug notification because you are subscribed to linux in Ubuntu. Matching subscriptions: Bgg, Bmail, Nb https://bugs.launchpad.net/bugs/2167160 Title: [HawkPoint1 1002:1900] gfx_0.0.0 timeout, failed MES ring reset, then GNOME Shell SIGABRT and session loss Status in linux package in Ubuntu: New Bug description: Suggested package: linux (Ubuntu), Ubuntu 26.04 / Resolute. Two AMDGPU hangs on this laptop ended the GNOME Wayland login session while the kernel continued running. The second occurred during ordinary terminal use, despite a previously installed Ptyxis Cairo-renderer workaround. ## System - Lenovo IdeaPad Slim 5 16AHP9, product 83DD; BIOS NGCN34WW, dated 2026-01-16. - AMD HawkPoint1, PCI 1002:1900 (rev cc), subsystem 17aa:3807; amdgpu. - Ubuntu 26.04.1 LTS; kernel 7.0.0-31-generic, Ubuntu package 7.0.0-31.31 (base 7.0.14). - GNOME Shell 50.1-0ubuntu1.2; Mutter 50.1-0ubuntu2.2; Wayland. - Mesa / mesa-libgallium 26.0.8-1ubuntu0.3; Ptyxis 50.1-1ubuntu2. - AMD firmware: linux-firmware-amd-graphics 20260319.git217ca6e4-0ubuntu3.1. - Internal eDP panel only at inspection time; boot log reports PSR support 0. - No amdgpu overrides appear in the kernel command line. GPU performance policy is auto; ppfeaturemask is 0xfff7bfff. These versions match the released Ubuntu archive as checked on 2026-09-12. Package integrity verification reported no discrepancies for Mesa Gallium, Mesa DRI/Vulkan, libdrm-amdgpu, Mutter, Shell and AMD graphics firmware. ## What happened On 2026-09-12 at 10:27:02 UTC, the graphics ring timed out, naming GNOME Shell PID 10699 and its graphics-submission thread 10716. MES did not respond to RESET and then repeatedly failed REMOVE_QUEUE. A MODE2 GPU reset succeeded at 10:27:31. GNOME Shell reported loss of an innocent graphics context and aborted. At 10:27:39 systemd recorded status 6/ABRT for the Shell service; Ptyxis lost its Wayland compositor connection. The login session ended at 10:27:41, and a new login began at 10:28:22. The kernel did not reboot; its boot began on 2026-09-11 at 16:20:43 UTC. No preceding GPU page fault, DMCUB/flip timeout, kernel OOM kill or systemd-oomd kill was found in the inspected logs for this incident. A previous event on 2026-09-11 at 12:03:49 UTC, on the same kernel version, named Ptyxis in its gfx_0.0.0 timeout and also required a GPU reset. ## Symbolized Shell backtrace The crashing thread is LWP 10716, matching the submission thread named in the timeout. Matching Ubuntu Mesa debug symbols were selected by build ID b089ec2f62ded38e9327502246aa4ccfb7929b24: ``` abort() amdgpu_ctx_set_sw_reset_status() at amdgpu_cs.cpp:491 amdgpu_cs_submit_ib<(queue_type)0>() at amdgpu_cs.cpp:2113 util_queue_thread_func() at u_queue.c:294 impl_thrd_routine() at threads_posix.c:43 ``` The matching Mesa 26.0.8 source identifies line 2113 as the -ECANCELED / PIPE_INNOCENT_CONTEXT_RESET path. The subsequent abort explains the session loss. It does not establish what originally hung the graphics ring. ## Trigger and mitigation already tried The user was working with Codex CLI in Ptyxis when the second event occurred. There is no reliable reproduction command, and Codex is not established as the cause. These are two observed incidents, not a controlled reproduction. After the first incident, a user-local Ptyxis wrapper selected GSK_RENDERER=cairo and a D-Bus override routed desktop activation through it. Both were installed before the next boot. After the second incident and new login, the running Ptyxis process had GSK_RENDERER=cairo and no open /dev/dri/ handles. The closed terminal's environment cannot be checked retrospectively. The workaround's installation has therefore not established system stability. Enabled Shell extensions at inspection time: ``` monitor@astraext.github.io ding@rastersoft.com snapd-prompting@canonical.com snapd-search-provider@canonical.com tiling-assistant@ubuntu.com ubuntu-appindicators@ubuntu.com ubuntu-dock@ubuntu.com web-search-provider@ubuntu.com ``` A comparison with extensions disabled has not been performed. Neither has a newer/mainline kernel test. The GPU device coredump expired before it was saved. Selected journals and the symbolized userspace backtrace are attached. ## Related reports and requested next step These reports have related symptoms but are not established duplicates: - https://gitlab.freedesktop.org/mesa/mesa/-/work_items/15668 — same GPU family and graphics-ring/MES recovery signature, with a different game trigger. - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2158614 — innocent-context abort and session loss, on a different GPU with preceding Chrome page faults. Ubuntu Proposed currently has kernel 7.0.0-38.38, whose changelog includes AMD gfx11 queue-interrupt fixes. Is that the appropriate next comparison for this hardware, or should the next step be a specific Mesa/firmware test or additional diagnostics? No particular fix or initiating defect is claimed. This report was prepared with AI assistance from the user's local journals and existing crash dump. Raw process environments and memory dumps are not included in the attached text.

Observe laggy input and check dmesg for "incomplete report" errors === HID DEVICE INFO === $ cat /sys/bus/hid/devices/0018:04F3:442A.0003/uevent DRIVER=hid-multitouch HID_ID=0018:000004F3:0000442A HID_NAME=ELAN2514:00 04F3:442A HID_PHYS=i2c-ELAN2514:00 HID_UNIQ= MODALIAS=hid:b0018g0004v000004F3p0000442A === HID REPORT DESCRIPTOR (base64, 1173 bytes) === BQ0JBKEBhQEFDQkioQIJQhUAJQF1AZUBgQJ1AYEDdQUJUSU/gQJ1AQlHJQGBAqQm/wB1CFUPZRE2 AABG/wAJSIECCUmBApUBBQEmEA51EFUPZREJMDUARi4BlQKBAibQCEa9AAkxgQK0wAUNCSKhAglC FQAlAXUBlQGBAnUBgQN1BQlRJT+BAnUBCUclAYECpCb/AHUIVQ9lETYAAEb/AAlIgQIJSYEClQEF ASYQDnUQVQ9lEQkwNQBGLgGVAoECJtAIRr0ACTGBArTABQ0JIqECCUIVACUBdQGVAYECdQGBA3UF CVElP4ECdQEJRyUBgQKkJv8AdQhVD2URNgAARv8ACUiBAglJgQKVAQUBJhAOdRBVD2URCTA1AEYu AZUCgQIm0AhGvQAJMYECtMAFDQkioQIJQhUAJQF1AZUBgQJ1AYEDdQUJUSU/gQJ1AQlHJQGBAqQm /wB1CFUPZRE2AABG/wAJSIECCUmBApUBBQEmEA51EFUPZREJMDUARi4BlQKBAibQCEa9AAkxgQK0 wAUNCSKhAglCFQAlAXUBlQGBAnUBgQN1BQlRJT+BAnUBCUclAYECpCb/AHUIVQ9lETYAAEb/AAlI gQIJSYEClQEFASYQDnUQVQ9lEQkwNQBGLgGVAoECJtAIRr0ACTGBArTABQ0JVlUAZQAn////f5UB dSCBAglUJX+VAXUIgQKFCglVJQqxAoVEBgD/CcUVACb/AHUIlgABsQLABv8BCQGhAYUCFQAm/wB1 CJVACQCBAsAGAP8JAaEBhQN1CJUgCQGRAsAFDQkCoQGFBzUACSChAAkyCUIJRAk8CUUJWhUAJQF1 AZUGgQKVAoEDBQEJMHUQlQGkVQ9lEUYuASYAS4FCCTFGvQAmAC+BQrQFDQkwJgAQgQJ1CJUBCTsm /wCBQnUQlQEJPaRlFFUONtjcRigjFtjcJigjgQIJPoECNQBHoIwAABUAJ6CMAAAJP4ECtAlWVQxm ARAn//8AAEf//wAAlgEAdRCBAgYA/3UIlQIJAYECwMAGAP8JgaEBhRd1CJVACQWBAsB1CBUAJv8A Bgv/CQuhAZUCCUiFSLEClQ8JKYUpsQKVHwkqhSqxApU+CSuFK7EClf4JLIUssQKW/gEJLYUtsQKV DwkuhS6BApUfCS+FL4EClT4JMIUwgQKV/gkxhTGBApb+AQkyhTKBApb+AwkzhTOBApb+Bwk0hTSB Apb+Dwk1hTWBApY/HQk2hTaBAsAGD/8JYKEBhRl1CJUEFQAm/wAJAJEChRl1CJUEFQAm/wAJxoEC wAYP/wlQoQGFInUglQEXAAAAgCf///9/CXKBAglzgQIJdIECCXWBAsAFAQkGoQGFEQUHGeAp5xUA JQF1AZUIgQKVA3UIFQAlcBkAKXCBAMAFDAkBoQGFEgnpCeoJ4gnNFQAlAXUBlQSBApUcgQPABQEJ AqEBhRMJAaEABQkZASkFFQAlAXUBlQWBApUDgQMFAQkwCTEJOBWBJX91CJUDgQbAwAYE/wnzoQGF RRUAJv8AdQiVHwn1gQLABgT/CfShAYVGdQiVIAn2kQLA === BOOT LOGS (relevant excerpt) === i2c_hid_acpi i2c-ELAN2514:00: i2c_hid_get_input: IRQ triggered but there's no data input: ELAN2514:00 04F3:442A Touchscreen as /devices/pci0000:00/0000:00:19.0/i2c_designware.2/i2c-2/i2c-ELAN2514:00/0018:04F3:442A.0003/input/input11 input: ELAN2514:00 04F3:442A as /devices/pci0000:00/0000:00:19.0/i2c_designware.2/i2c-2/i2c-ELAN2514:00/0018:04F3:442A.0003/input/input12 input: ELAN2514:00 04F3:442A Stylus as /devices/pci0000:00/0000:00:19.0/i2c_designware.2/i2c-2/i2c-ELAN2514:00/0018:04F3:442A.0003/input/input13 input: ELAN2514:00 04F3:442A UNKNOWN as /devices/pci0000:00/0000:00:19.0/i2c_designware.2/i2c-2/i2c-ELAN2514:00/0018:04F3:442A.0003/input/input27 input: ELAN2514:00 04F3:442A UNKNOWN as /devices/pci0000:00/0000:00:19.0/i2c_designware.2/i2c-2/i2c-ELAN2514:00/0018:04F3:442A.0003/input/input30 input: ELAN2514:00 04F3:442A UNKNOWN as /devices/pci0000:00/0000:00:19.0/i2c_designware.2/i2c-2/i2c-ELAN2514:00/0018:04F3:442A.0003/input/input31 input: ELAN2514:00 04F3:442A UNKNOWN as /devices/pci0000:00/0000:00:19.0/i2c_designware.2/i2c-2/i2c-ELAN2514:00/0018:04F3:442A.0003/input/input32 hid-multitouch 0018:04F3:442A.0003: input,hidraw2: I2C HID v1.00 Keyboard [ELAN2514:00 04F3:442A] on i2c-ELAN2514:00 [When using stylus:] i2c_hid_acpi i2c-ELAN2514:00: i2c_hid_get_input: incomplete report (67/5631) i2c_hid_acpi i2c-ELAN2514:00: i2c_hid_get_input: incomplete report (67/5631) [...repeated many times...] === LIBINPUT INFO === Device: ELAN2514:00 04F3:442A Stylus Kernel: /dev/input/event12 Id: i2c:04f3:442a Group: 8 Seat: seat0, default Size: 300x188mm Capabilities: tablet === LOADED MODULES === $ lsmod | grep -E "hid|multitouch" hid_multitouch 36864 0 i2c_hid_acpi 12288 0 i2c_hid 49152 1 i2c_hid_acpi Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2142384/comments/0 ------------------------------------------------------------------------ On 2026-03-11T20:56:26+00:00 lr6183286 wrote: I want to add that this is also affecting the HP Omnibook 7 Flip 16t-au000 with same outputs as the bug report had presented.

[Bug 2167177] [NEW] Intermittent SPI keyboard/trackpad failure at boot — DMA/PIO module load order race in spi_pxa2xx_pci

Public bug reported: On a MacBook8,1 (2016 12" MacBook, Intel Broadwell), the internal SPI keyboard and trackpad intermittently fail to initialize at boot. A restart always resolves the issue. The failure is caused by a race between dw_dmac_pci and pxa2xx_spi_pci module probe order. Symptoms: Intermittent: keyboard and trackpad not detected after boot (no input: Apple SPI Keyboard / input: Apple SPI Touchpad in dmesg) Restart always fixes it No external keyboard required to reproduce (it's a boot-time race) Root Cause: The spi_pxa2xx_pci driver checks for DMA channel availability at probe time. The outcome depends on whether dw_dmac_pci has already registered its channels: Good boot: pxa2xx_spi_pci probes first → "no DMA channels available, using PIO" → works Bad boot: dw_dmac_pci probes first → SPI sees DMA → uses DMA → transfers time out (-110) → driver re-queues a message still linked in the SPI core's list → list corruption (__list_add_valid_or_report warning) → driver is permanently stuck Failed boot log (kernel 7.0.0-31-generic): dw_dmac_pci 0000:00:15.0: DesignWare DMA Controller, 8 channels input: Apple SPI Keyboard as /devices/pci0000:00/0000:00:15.4/spi_master/spi1/spi-APP000D:00/input/input4 applespi spi-APP000D:00: SPI transfer timed out applespi spi-APP000D:00: Error writing to device: -110 spi_master spi1: failed to transfer one message from queue applespi spi-APP000D:00: SPI transfer timed out applespi spi-APP000D:00: Error reading from device: -110 WARNING: lib/list_debug.c:35 at __list_add_valid_or_report+0xc6/0xe0, CPU#3: spi1/455 spi_queued_transfer+0xed/0x110 __spi_async+0xd5/0x160 spi_async+0xd6/0xe0 applespi_send_cmd_msg+0x17d/0x400 [applespi] applespi_msg_complete+0xc5/0x110 [applespi] applespi_async_read_complete+0x5c/0x60 [applespi] spi_master spi1: failed to transfer one message from queue applespi spi-APP000D:00: SPI transfer timed out applespi spi-APP000D:00: Error writing to device: -110 Successful boot log (same kernel, same machine): pxa2xx_spi_pci 0000:00:15.4: no DMA channels available, using PIO dw_dmac_pci 0000:00:15.0: DesignWare DMA Controller, 8 channels input: Apple SPI Keyboard as /devices/pci0000:00/0000:00:15.4/spi_master/spi1/spi-APP000D:00/input/input4 applespi spi-APP000D:00: Received corrupted packet (crc mismatch) applespi spi-APP000D:00: modeswitch done. input: Apple SPI Touchpad as /devices/pci0000:00/0000:00:15.4/spi_master/spi1/spi-APP000D:00/input/input5 Upstream Status: The list-corruption bug (re-queueing applespi->wr_m via spi_async() while still linked in SPI core lists) was identified in the sashiko-bot review of the v4/v5 patch series (Shih-Yuan Lee, July 2026, linux-spi mailing list).
