I can reproduce the issue on latest firmware ("amdgpu: update vega20 ucode for
19.30") and latest amd-staging-drm-next ("drm/amdgpu: remove redundant variable
r and redundant return statement").

I don't see keep trying latest kernel/firmware makes us going anywhere. If you
need a physical hardware to debug, please just let me know.
