I reverted it and Linux 5.6-rc1 no longer hangs on reboot/poweroff git bisect bad a655a99c9f6a1d819d695fca6d48b450449f45ee is the first bad commit Okay success. I reverted it and Linux 5.6-rc1 no longer hangs on reboot/poweroff I am building Linux 5.7-rc1 with this reverted now. Details and full bisect log. I am building Linux 5.7-rc1 with this reverted now. commit a655a99c9f6a1d819d695fca6d48b450449f45ee Author: Prike Liang Date: Tue Apr 7 20:21:26 2020 +0800 drm/amdgpu: fix gfx hang during suspend with video playback (v2) [ Upstream commit 487eca11a321ef33bcf4ca5adb3c0c4954db1b58 ] The system will be hang up during S3 suspend because of SMU is pending for GC not respose the register CP_HQD_ACTIVE access request.This issue root cause of accessing the GC register under enter GFX CGGPG and can be fixed by disable GFX CGPG before perform suspend. v2: Use disable the GFX CGPG instead of RLC safe mode guard.
