6.1.0-1004-oem worked fine in terms of stability over yesterday's work day, with no amdgpu protection faults, but when I tried to suspend by closing the lid at the end of the work day, I got some very strange behaviour that I've never seen before - see video here: https://photos.app.goo.gl/hkyy9a9U2jJ7GPL59 I'll test your custom 5.17 kernel next, because it seems that the 5.17 train is the only viable one at the moment on this hardware. I reverted to 5.17.0-1025-eom today and everything went fine. As a point of comparison, I'm updating this bug on my personal laptop, which is a ThinkPad E14 AMD Gen3 - very similar specs to my work laptop, yet this one suspends fine on 6.1.0-1004-oem and has had no amdgpu problems that I know of.

Hi Acelan,
The first bad commit:
commit 224dffc89a957e2f006de3202d12c09bf348f992 (refs/bisect/bad)
Author: Alex Deucher
Date: Wed Dec 21 15:26:47 2022 +0800
drm/amdgpu: make sure to init common IP before gmc
BugLink: https://launchpad.net/bugs/2000110
Move common IP init before GMC init so that HDP gets
remapped before GMC init which uses it.
This fixes the Unsupported Request error reported through
AER during driver load. The error happens as a write happens
to the remap offset before real remapping is done.
Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373
The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather
fixes the issue in amdgpu exposed by the commit. The reference is only
to associate this commit with below one so that both go together.
