Hi Alex, hi all

In Debian we got a regression report from Dominique Dumont, CC'ed in
https://bugs.debian.org/1005005 that afer an update to 5.15.15 based
kernel, his machine noe longer suspends correctly, after screen going
black as usual it comes back. The Debian bug above contians a trace.

Dominique confirmed that this issue persisted after updating to 5.16.7
furthermore he bisected the issue and found 

	3c196f05666610912645c7c5d9107706003f67c3 is the first bad commit
	commit 3c196f05666610912645c7c5d9107706003f67c3

	    drm/amdgpu: always reset the asic in suspend (v2)

	    [ Upstream commit daf8de0874ab5b74b38a38726fdd3d07ef98a7ee ]

	    If the platform suspend happens to fail and the power rail
	    is not turned off, the GPU will be in an unknown state on
	    resume, so reset the asic so that it will be in a known
	    good state on resume even if the platform suspend failed.

	    v2: handle s0ix

to be the first bad commit, see https://bugs.debian.org/1005005#34 .

Does this ring any bell? Any idea on the problem?
