It's not a straight "git revert" on 6.8-rc1 because of some other 
contextual changes.

I posted that as an RFC specifically "in case" that's the direction we 
go and don't get a proper solution together.

Matthew also posted a debugging patch here for use with ftrace and the 
GPU scheduler events: https://gitlab.freedesktop.org/drm/amd/-/issues/3124

I reproduced it with that as well and posted my ftrace results.
