I've reported this 2 times to amd-gfx-devel (Alex, Harry et al.) in the last
several days. Was '[amd-staging-drm-next] kernel crash with amdgpu on RX580 in
'drm_object_property_get_value'.

Should be 'drm_object_property_[get|set]_value'.

Yes, it is _NO_ crash only warning (my bad) and it is _WORKED_ on.

Here comes what Alex mailed me about:
