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.

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.
