This is a regression introduced in 6.8-rc1, bisected from 6.7.
This revert done on top of 6.8-rc1 fixes the issue.
Applying this revert on 6.8-rc1 fixed my issues reported here:
https://lore.kernel.org/all/2faccc1a-7fdd-499b-aa0a-bd54f4068f3e@xxxxxxx/
Let me know if there's another fix instead of revert so I can test.
There's not another fix at the moment, but Matthew has posted a patch to
allow ftrace to capture more data with the gpu_scheduler trace events to
this bug report:
https://gitlab.freedesktop.org/drm/amd/-/issues/3124
I already captured from a local machine and attached to that bug report.
Thanks,
Vlastimil
I'm happy to gather any data to use to properly debug if that is
preferable to a revert.
