Compiled and booted on my test system. No dmesg regressions.
I made some progress on the drm/amdgpu display and kepboard
problem.
My system has
amdgpu: ATOM BIOS: 113-RENOIR-026
I narrowed it down to the following as a possible lead to
start looking:
amdgpu 0000:0b:00.0: [drm] Cannot find any crtc or sizes
It is resolved now. A hot-unplugged/plugged the HDMI cable which
triggered reset sequence. There might be link to AMD_DC_HDCP
support, amdgpu_dm_atomic_commit changes that went into 5.10 and
this behavior.
I am basing this on not seeing the problem on Linux 5.4 and until
Linux 5.10. In any case, I wish I know more, but life is back to
normal now.
When I hot-unplugged/plugged the cable, saw the following dmesg:
amdgpu 0000:0b:00.0: [drm] fb0: amdgpudrmfb frame buffer device
