Hi all,
TL;DR - git bisection points to
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.15.4&id=61d861cf478576d85d6032f864360a34b26084b1
as causing an issue when changing power state after idle.
Since 5.15.0 I have had intermittent issues with my GPU failing to
resume after entering power saving. I have errors like these:

this eventually leads to processes crashing, and the system locking up
during shutdown.
A git bisection has isolated the following patch as the cause.

drm/amd/display: Move AllowDRAMSelfRefreshOrDRAMClockChangeInVblank
to bounding box
[Why]
This is a global parameter, not a per pipe parameter and it's useful
for experimenting with the prefetch schedule to be adjustable from
the SOC bb.
[How]
Add a parameter to the SOC bb, default is the existing policy for
all DCN. Fill it in when filling SOC bb parameters.
Revert the policy to use MinDCFClk at the same time since that's not
going to give us P-State in most cases on the spreadsheet.

I have been running 5.15.4 with 61d861cf478576d85d6032f864360a34b26084b1
backed out for a few hours with multiple periods of power saving, and so
far so good.
Cheers,
Mark
