Thanks, I'll try it when I get home. Meanwhile reverting to 6.3.8 seems to have solved it for now as well. A little more information: The bug was reported and confirmed on the Freedesktop Gitlab: https://gitlab.freedesktop.org/drm/amd/-/issues/2658 Reports also start piling up on Arch, Fedora etc. bsc#1212833 seems to be a duplicate. Same symptoms, same time of appearing (6.3.9) and always with the amdgpu module loaded.
