I had been testing some things on a post 6.6-rc5 kernel for a week or

system suspend was broken. It seems that the radeon driver failed to
suspend, leaving the display dead, the wayland display server hung, and
the system still running. I have been trying to bisect it for the last
few days and have only been able to narrow it down to the following 3
commits:
There are only 'skip'ped commits left to test.
The first bad commit could be any of:

c07bf1636f0005f9eb7956404490672286ea59d3

We cannot bisect more!
Hmm, not a single reply from the amdgpu folks. Wondering how we can
encourage them to look into this.
Phillip, reporting issues by mail should still work, but you might have
more luck here, as that's where the amdgpu afaics prefer to track bugs:
https://gitlab.freedesktop.org/drm/amd/-/issues
When you file an issue there, please mention it here.
Furthermore it might help if you could verify if 6.7-rc1 (or rc2, which
comes out later today) or 6.6.2-rc1 improve things.
It would also be good to test if reverting any of these is possible or not.
Well none of the commits mentioned can affect radeon in any way. Radeon
simply doesn't use the scheduler.
My suspicion is that the user is actually using amdgpu instead of
radeon. The switch potentially occurred accidentally, for example by
compiling amdgpu support for SI/CIK.
Those amdgpu problems for older ASIC have already been worked on and
should be fixed by now.
In this case it's a navi23 (so radeon in the marketing sense).
Thanks, couldn't find that in the mail thread.
In that case those are the already known problems with the scheduler
changes, aren't they?

File the gitlab issue and we should poke amd a but more to take a look.
