dmesg

Computer fails to resume from suspend.
>From the logs it looks like AMDGPU fails to resume.

It is a thinkpad T14 AMD APU R7 4750U, connected to an external display via
USB-C port thru an adapter.

I can still ssh to the machine after resume action, but the both internal
display and external display stuck at black screen.
