Trying to `git am` the rxrpc fix caused a merge conflict unless on the master branch. I had to cherry-pick 6 other patches, unless someone looks at the code. My work is at https://github.com/linux-surface/linux- surface/pull/2117/changes and I have 8 kernel patches. This covers both the rxrpc and esp parts of the dirty frag vulnerability. The mainline 6.18 kernel builds successfully, but I haven't tested it at runtime. -- You received this bug notification because you are subscribed to linux in Ubuntu.

[Bug 2152145] [NEW] Regression: i915 GPU hang/freeze on Intel Kaby Lake during Remmina RDP session in Ubuntu 26.04
Public bug reported: Hardware: ASUS UX331UA, Intel Core (Kaby Lake), i915 graphics. OS: Ubuntu 26.04 (Kernel 7.x) Issue Description: The system completely freezes (cursor hangs, deadlock, requires a hard hardware reboot) when using Remmina (RDP protocol). The crash consistently happens during sudden GUI updates inside the RDP session (e.g., printing to PDF from a remote Windows application and closing the dialog window). Troubleshooting done: Tried kernel parameters: i915.enable_psr=0, intel_idle.max_cstate=1, i915.enable_guc=0, i915.enable_dc=0 – None of these prevented the crash. Switching to an external FHD monitor (via direct HDMI) instead of a 2K display did not resolve the issue. The Regresion Proof: When I boot into the older kernel (the one carried over from Ubuntu 25.10), the system is 100% stable. The RDP session works flawlessly, and printing to PDF does not crash the system. Conclusion: This is a severe regression in the newer kernel provided in Ubuntu 26.04, likely related to the i915 driver's memory management (TTM) or rendering instructions during large screen redraws on Kaby Lake architecture.

I can tap or drag the finger and it does not register the finger touch so I cannot move the pointer much, if at all. it is a click pad and often will register the initial moment my finger touches the pad AND the click together treating them as a double click. It very often fails to register two finger taps, or multi finger gestures for scrolling or exposing the desktop or whatever. It is super sensitive and sometimes registers the proximity of my hand (without actually touching it) as a touch making the cursor jump around. This is incredibly frustrating as it often means I am fixing typos where the cursor jumps, or fixing issues where it regitsers an action to highlight an entire line causing me to lose the line on the next keypress (as in highlight and replace/type over. all of this is intermittent. I usually use the machine at home when docked (FYI for some reason it just triggered the highlight entire line and deleted this sentence and I had to retype it.). When docked I'm using an external BT mouse so I dont notice issues. But both times Ive traveled with this machine I've had an incredibly frustrating experience with the trackpad and how it behaves.CLOSE For context it has taken me twice as long to type this out as it should because I have to keep correcting issues where the trackpad is jumping the mouse around, and other issues. Right now, two finger scrolling is not working at all... it just randomly stopped working yesterday. Just a moment ago, it somehow started triggering moving through tabs on my browser when I used a single finger touch/drag to move the cursor through this text box... sigh... and it sometimes fails to even register the click action on the clickpad, making me instead try to remember using the actual buttons to perform click actions instead of hoping that either tap or click on the pad itself will work.

[Bug 2138991] Re: Dell 16 Premium DA16250 webcam (OV02C10) not working - INT3472 GPIO type 0x02 unknown
Status changed to 'Confirmed' because the bug affects multiple users. ** Changed in: linux (Ubuntu Noble) Status: New => Confirmed -- You received this bug notification because you are subscribed to linux in Ubuntu. Matching subscriptions: Bgg, Bmail, Nb https://bugs.launchpad.net/bugs/2138991 Title: Dell 16 Premium DA16250 webcam (OV02C10) not working - INT3472 GPIO type 0x02 unknown Status in ipu6-drivers package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in ipu6-drivers source package in Noble: Confirmed Status in linux source package in Noble: Confirmed Bug description: ## Description ### Summary The integrated webcam on Dell 16 Premium (DA16250) with Intel Meteor Lake CPU does not work on Ubuntu 24.04 with OEM kernel. The camera sensor (OV02C10) is detected but fails to initialize due to unsupported GPIO type 0x02 in the INT3472 discrete driver. ### System Information - **Hardware:** Dell 16 Premium DA16250 - **CPU:** Intel Core Ultra 9 285H (Meteor Lake) - **Camera Sensor:** OmniVision OV02C10 (ACPI: OVTI02C1:00) - **OS:** Ubuntu 24.04.3 LTS - **Kernel:** 6.14.0-1019-oem ### Steps to Reproduce 1. Install Ubuntu 24.04 on Dell 16 Premium DA16250 2. Install OEM kernel: `sudo apt install linux-oem-24.04` 3. Install IPU6 modules: `sudo apt install linux-modules-ipu6-6.14.0-1019-oem` 4. Install camera HAL: `sudo apt install libcamhal-ipu6epmtl` (from OEM PPA) 5. Reboot and try to use the webcam ### Expected Behavior Webcam should be detected and functional in applications like Cheese, Firefox, Chromium. ### Actual Behavior Camera is detected by the IPU6 driver but fails to initialize. The sensor does not register in the media pipeline. ### Error Messages (from dmesg) ``` int3472-discrete INT3472:0c: GPIO type 0x02 unknown; the sensor may not work intel-ipu6 0000:00:05.0: Found supported sensor OVTI02C1:00 intel-ipu6 0000:00:05.0: Connected 1 cameras ``` ### Error Messages (from GStreamer test) ``` CamHAL[INF] aiqb file name AR0234_TGL_10bits.aiqb CamHAL[ERR] Stream config is not supported. format:V4L2_PIX_FMT_NV12 (1920x1080) ``` The camera HAL loads the wrong config file (AR0234 instead of OV02C10) because the sensor is not bound to the I2C bus. ### Diagnosis The ov02c10 kernel module is loaded but not bound to any device: ``` $ ls /sys/bus/i2c/drivers/ov02c10/ bind module uevent unbind ``` The ACPI device exists and is enabled (status 15): ``` $ cat /sys/bus/acpi/devices/OVTI02C1:00/status 15 ``` But there is no physical_node because the INT3472 GPIO initialization fails. ### Root Cause GPIO type 0x02 is a "strobe" GPIO used for LED/IR control on Meteor Lake systems. The int3472-discrete driver does not recognize this GPIO type, preventing proper camera power-up. ### Existing Kernel Patch A patch exists that adds support for GPIO type 0x02 (strobe): https://patchwork.kernel.org/project/linux-media/patch/20231007021309.9332-1-hao.yao@intel.com/ ### Related Issues - Intel IPU6 drivers: https://github.com/intel/ipu6-drivers/issues/413 - Intel IPU6 drivers: https://github.com/intel/ipu6-drivers/issues/40 - Ubuntu Bug #2117188: https://bugs.launchpad.net/ubuntu/+source/ipu6-drivers/+bug/2117188 ### Workarounds Attempted (None Successful) 1. Added `intel_iommu=on` to kernel parameters 2. Fixed /dev/ipu-psys0 permissions with udev rules 3. Installed libcamhal-ipu6epmtl from OEM PPA 4. Tried Dell OEM archive packages ### Request Please backport the INT3472 GPIO strobe patch to the Ubuntu OEM kernel to support Dell 16 Premium and other Meteor Lake laptops with OV02C10 cameras. ## Attachments ### uname -a ``` Linux Dell-16-Premium-DA16250 6.14.0-1019-oem #19-Ubuntu SMP PREEMPT_DYNAMIC Thu Dec 18 05:40:21 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux ``` ### CPU Info ``` vendor_id : GenuineIntel cpu family : 6 model : 197 model name : Intel(R) Core(TM) Ultra 9 285H ``` ### lspci (IPU6 device) ``` 0000:00:05.0 Multimedia controller [0480]: Intel Corporation Device [8086:7d19] (rev 05) Subsystem: Dell Device [1028:0ce7] Flags: bus master, fast devsel, latency 0, IRQ 16, IOMMU group 3 Memory at 581c000000 (64-bit, non-prefetchable) [size=16M] Kernel driver in use: intel-ipu6 Kernel modules: intel_ipu6 ``` ### dmesg (camera related) ``` [ 16.744854] int3472-discrete INT3472:0c: GPIO type 0x02 unknown; the sensor may not work [ 16.764935] intel-ipu6 0000:00:05.0: enabling device (0000 -> 0002) [ 16.781627] intel-ipu6 0000:00:05.0: Found supported sensor OVTI02C1:00 [ 16.781717] intel-ipu6 0000:00:05.0: Connected 1 cameras [ 16.784617] intel-ipu6 0000:00:05.0: Sending BOOT_LOAD to CSE [ 16.821495] intel-ipu6 0000:00:05.0: Sending AUTHENTICATE_RUN to CSE [ 16.879001] intel-ipu6 0000:00:05.0: CSE authenticate_run done [ 16.879013] intel-ipu6 0000:00:05.0: IPU6-v4[7d19] hardware version 6 [ 17.565317] intel_ipu6_psys.psys intel_ipu6.psys.40: pkg_dir entry count:8 [ 17.565808] intel_ipu6_psys.psys intel_ipu6.psys.40: psys probe minor: 0 [ 2663.927955] intel-ipu6 0000:00:05.0: IPU6 in secure mode [ 7592.628584] intel-ipu6 0000:00:05.0: IPU6 in secure mode ``` ### Installed packages (camera related) ``` ii gstreamer1.0-icamera 0~git202509260937.4fb31db~ubuntu24.04.7 amd64 ii libcamhal-common 0~git202601200757.9899efa~ubuntu24.04.1 all ii libcamhal-ipu6ep 0~git202601200757.9899efa~ubuntu24.04.1 amd64 ii libcamhal-ipu6epmtl 0~git202601200757.9899efa~ubuntu24.04.1 amd64 ii libcamhal0 0~git202601200757.9899efa~ubuntu24.04.1 amd64 ii linux-image-6.14.0-1019-oem 6.14.0-1019.19 amd64 ii linux-image-6.14.0-37-generic 6.14.0-37.37~24.04.1 amd64 ii linux-image-generic-hwe-24.04 6.14.0-37.37~24.04.1 amd64 ii linux-image-oem-24.04 6.14.0-1019.19 amd64 ii linux-modules-6.14.0-1019-oem 6.14.0-1019.19 amd64 ii linux-modules-6.14.0-37-generic 6.14.0-37.37~24.04.1 amd64 ii linux-modules-extra-6.14.0-37-generic 6.14.0-37.37~24.04.1 amd64 ii linux-modules-ipu6-6.14.0-1019-oem 6.14.0-1019.19 amd64 ``` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ipu6-drivers/+bug/2138991/+subscriptions
