I experienced this sudden iGPU performance drop (1FPS) today on my AMD Framework 13 running Fedora 40
(Gnome Wayland), kernel 6.9.5
, amd-gpu-firmware 20240709-1.fc40
.
This was also spammed in my system journal:
amdgpu 0000:c1:00.0: [drm] *ERROR* Error queueing DMUB command: status=2
Here’s a runtime solution (no reboot required) which worked for me:
$ sudo cat /sys/kernel/debug/dri/1/amdgpu_gpu_recover
The screen then goes black for a second and comes back with restored GPU performance.
Hope this helps!
