https://bugzilla.kernel.org/show_bug.cgi?id=201957 --- Comment #74 from Martin von Wittich (martin.von.wittich@xxxxxxxx) --- > Did you try with the latest Linux Kernel? I had a lot of gpu lockups like this. Also try these kernel parameters : "amdgpu.ppfeaturemask=0xffffbffb amdgpu.noretry=0 amdgpu.lockup_timeout=0 amdgpu.gpu_recovery=1 amdgpu.audio=0 amdgpu.deep_color=1 amd_iommu=on iommu=pt"" ( you might also try with amdgpu.ppfeaturemask=0xfffd7fff or amdgpu.ppfeaturemask=0xffffffff ) I can confirm that at least on the current Ubuntu linux-image-oem-20.04d kernel, these options do not resolve the issue: ``` martin@martin ~ % uname -a Linux martin 5.14.0-1042-oem #47-Ubuntu SMP Fri Jun 3 18:17:11 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux martin@martin ~ % cat /proc/cmdline BOOT_IMAGE=/vmlinuz-5.14.0-1042-oem root=UUID=1bd000ac-1487-4457-be1a-5ea901ded9e9 ro amdgpu.ppfeaturemask=0xffffbffb amdgpu.noretry=0 amdgpu.lockup_timeout=0 amdgpu.gpu_recovery=1 amdgpu.audio=0 amdgpu.deep_color=1 amd_iommu=on iommu=pt quiet martin@martin ~ % dmesg -T | grep 'ring gfx timeout' [Mi Jun 22 14:48:07 2022] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=1820983, emitted seq=1820985 [Mi Jun 22 14:48:18 2022] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=1820987, emitted seq=1820990 ``` I had enabled these options on 2022-06-20 14:14 UTC+2, this is the first crash I've encountered since then. I have no idea how to build the latest kernel and therefore haven't tested that yet. I'll now revert back to amdgpu.dpm=0. -- You may reply to this email to add a comment.
