dmesg of loading amdgpu module with patch 218586
I tried git://people.freedesktop.org/~agd5f/linux on amd-staging-drm-next
branch. The last commit is "905aa01b240f9216b6dbba3226bf10b2d96eebb7
drm/amd/display: clean up assignment of amdgpu_crtc" which contains the patch
<a href="https://patchwork.freedesktop.org/patch/218586/">https://patchwork.freedesktop.org/patch/218586/</a> .
However, the system still hung up with the following error. The attachment is
the full dmesg.
