<pre>This bug just occured spontaneously (while just using a text editor):
Aug 09 22:23:34 ryzen kernel: [drm:gfx_v8_0_priv_reg_irq [amdgpu]] *ERROR*
Illegal register access in command stream
Aug 09 22:23:34 ryzen kernel: amdgpu 0000:0a:00.0: GPU reset begin!
Aug 09 22:23:38 ryzen kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring
gfx timeout, signaled seq=193874, emitted seq=193874
Aug 09 22:23:38 ryzen kernel: amdgpu 0000:0a:00.0: GPU reset begin!
Aug 09 22:23:44 ryzen kernel: [drm:amdgpu_dm_atomic_check [amdgpu]] *ERROR*
[CRTC:44:crtc-0] hw_done or flip_done timed out
Kernel was compiled from amd-staging-drm-next as of commit
bf1fd52b0632cd17ac875432a36d3e92be96d8cb.
The RX 460 GPU was (a day before) manually set to lowest mclk/sclk with
cd /sys/class/drm/card0/device ; echo manual >power_dpm_force_performance_level
;
echo 0 >pp_dpm_mclk ; echo 0 >pp_dpm_sclk</pre>
