I confirm that the issue is this commit
It is a merge of many commits, and due to some git magic that I do not understand, I am unable to bisect inside this merge.
So instead I am trying to cherry picking all of the commits of this merge and recompiling after few cherry-pick, testing, etc.
There is definitely a lot of thing I do not understand on how git work. And really don’t understand why “git bisect” doesn’t give acceptable result
cherry picking until db70e2c13983926d8d657db3e740264b75ad20a4 : work
cherry picking until c16904b0f305c5f6bc31de118d4b1e60a5da5408: don’t work
The specific problematic commit of the merge seems to be 4fdda2e66de0b7d37aa27af3c1bbe25ecb2d5408
The problematic patch is

To fix my issue, I modified the integer comparison from
amdgpu_runtime_pm != 0 back to amdgpu_runtime_pm > 0
(reported to the amd driver issue tracker)
Now trying to apply this modification to the 6.1 kernel
