[Bug 2173636] Re: ITE Super I/O chip (IDs 0x8696 / 0x8883) unsupported on Gigabyte X870 AORUS ELITE WIFI7, causing sensor read-out failures and erratic maximum fan speed behavior

I doubt Ubuntu can/will do anything about this. I don't see support for the ITE8696 in latest kernel. ITE is not known to be friendly to open- source in terms of giving code or datasheets. Your best bet is probably the repo from Frank Crawford, which can be installed like: sudo apt install build-essential linux-headers-$(uname -r) dkms git cd ~/ && git clone https://github.com/frankcrawford/it87.git && cd it87/ sudo ./dkms-install.sh echo "options it87 mmio=on" | sudo tee /etc/modprobe.d/it87.conf echo "it87" | sudo tee /etc/modules-load.d/it87.conf sudo update-initramfs -u -k all (Reboot) Check output of: sensors But I don't think it has fan control support. Are you running the latest BIOS? ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are subscribed to linux in Ubuntu.

During hardware probing (sensors-detect), the system identifies unknown chips with IDs 0x8696 and 0x8883, but sensors cannot read subfeatures (such as fan1_min, fan1_max, and power caps), returning persistent N/A readouts and execution errors. Because the kernel cannot interface with these newer ITE chip IDs, the motherboard's Embedded Controller (EC) loses continuous communication with userspace sensors and repeatedly triggers a failsafe routine, forcing all system and CPU fans to run continuously at maximum speed (100% duty cycle) as a thermal protective measure. Full Incident History & Current Status: 1. Kernel Regressions: Kernel 7.0.0-42-generic was identified as problematic, placed on hold, and purged. The system was reverted to running on the older 7.0.0-38-generic kernel, but the underlying sensor communication failure persists on both kernel versions. 2. Failed Driver Compilation Attempts: Multiple attempts to compile and load community/third-party it87 drivers and DKMS modules via various GitHub repositories (ucw/it87, a1winston/it87-dkms, and hjlcmb/it87) continuously failed due to repository redirection/HTTP errors, missing dependencies/packages in Mint repositories, and authentication prompts. 3. Hardware Mitigation & Ongoing Instability Monitoring: To immediately suppress the extreme fan noise, a manual "Normal" fan profile was applied directly in the BIOS (Gigabyte Smart Fan 6). Following a complete cold shutdown and power cycle (which temporarily cleared the EC's locked failsafe state), the fan speeds currently appear to adhere to the hardware BIOS profile. However, the root cause at the kernel driver level remains entirely unresolved. Because userspace sensor readouts still output N/A, it is currently unknown whether the hardware-level BIOS override will hold over time or if the EC will trip back into maximum failsafe fan speeds during extended runtime or load. Environment & System Information: - OS / Release (lsb_release -rd): Linux Mint (Ubuntu-based distribution) - Kernel Signature (cat /proc/version_signature): Stored in version.log - Motherboard: Gigabyte X870 AORUS ELITE WIFI7 - Super I/O Chips: ITE IDs 0x8696 and 0x8883 - Processor: AMD Ryzen 7 9700X 8-Core Attached Logs: 1. version.log (generated via cat /proc/version_signature > version.log) 2. lspci-vnvn.log (generated via sudo lspci -vnvn > lspci-vnvn.log) Steps to Reproduce: 1. Boot into Linux Mint on a Gigabyte X870 AORUS ELITE WIFI7 motherboard. 2. Run sensors-detect --auto. 3. Observe Super I/O probe results identifying unsupported chip IDs 0x8696 and 0x8883. 4. Run sensors and observe N/A readouts and subfeature read errors (fan1_min, fan1_max, etc.). 5. Observe the Embedded Controller failing over to 100% max fan speeds (which currently requires a cold shutdown and manual BIOS curve forcing to temporarily suppress). Expected Behavior: The Linux kernel (or standard hwmon driver stack) should natively support ITE 0x8696 and 0x8883 chips to provide proper sensor telemetry, allowing controlled fan operation without relying on manual BIOS workarounds or risking EC failsafe lock-ins To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2173636/+subscriptions
