--- Comment #2 from Ethan ethan@esmth.us --- I am experiencing the exact same issue on my Dell Inspiron 3185 with a Stoney Ridge A9-9420e. I have tried multiple kernels and distributions and I experience the same freeze as described on resume from suspend. (I haven't found a setup that can resume from suspend at all.) On X11, the cursor still works but everything else on the display has hung. On wayland the whole display freezes on resume. I can get these lines in the kernel log though ssh after this happens:
[ 60.081396] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=379, emitted seq=382 [ 60.081550] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process Xorg pid 2030 thread Xorg:cs0 pid 2031 [ 60.081560] [drm] IP block:gfx_v8_0 is hung! [ 60.081637] [drm] GPU recovery disabled.
Passing amdgpu.gpu_recovery=1 to the kernel gets a larger kernel error message, but does not fix the issue.
