--- Comment #3 from Tom (tom at 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:
