Hi Zhuravlev, The information of test card is as following: Lspci name: [AMD/ATI] Vega 10 [Radeon Instinct MI25 MxGPU] (rev 05) Firmware: ATOM BIOS: 113-D0531800-C04 When run test scripts compute-rocm-*/utils/run_rsmitst.sh, the below test cases fail. [ FAILED ] 4 tests, listed below: [ FAILED ] rsmitstReadOnly.TestOverdriveRead [ FAILED ] rsmitstReadWrite.FanReadWrite [ FAILED ] rsmitstReadWrite.TestOverdriveReadWrite [ FAILED ] rsmitstReadWrite.TestPowerCapReadWrite Best Regards, Asher From: Yury Zhuravlev <stalk...@gmail.com> Sent: Wednesday, October 26, 2022 9:31 AM To: Song, Asher <asher.s...@amd.com> Cc: Deucher, Alexander <alexander.deuc...@amd.com>; Chen, Guchun <guchun.c...@amd.com>; Quan, Evan <evan.q...@amd.com>; amd-gfx@lists.freedesktop.org Subject: Re: [PATCH] drm/amdgpu: Revert "drm/amdgpu: getting fan speed pwm for vega10 properly" Hello, Can you write here your card name and firmware version? Without this patch, my fan sensors are broken, and it's sensitive to my pc case with water cooling. My card is: Sapphire Pulse Radeon RX Vega 56 vd6546 SA lspci name: [AMD/ATI] Vega 10 XL/XT [Radeon RX Vega 56/64] (rev c3) Firmware: ATOM BIOS: 113-376XL-UO2 This patch is 100% working correct on my machine, and I tested it last 2 months.

Unfortunately, that commit causes fan monitors can't be read and written properly.
