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.

Does it work without the external display connected?
Tried several times, Looks like no problem without the external display connected.
btw, I have kernel option amd_iommu=off and vt.handoff=7

--- Comment #3 from Tom (tom@collider.in) --- I am also affected by this. There are a few recent amdgpu suspend bugs open but this one is most similar.
My card is a Radeon R7 260X (Bonaire XTX [Radeon R7 260X/360]), so I'm using the experimental amdgpu driver support.
5.4.58 works, 5.4.72 does not, 5.9.1 does not.
My computer seems to be completely unresponsive after resuming. I haven't tried SSHing but it does not respond to pressing the power button to put it back into sleep. However there are systemd service logs in the journal after resume.
Kernel messages of note, which are not part of working logs:
