--- Comment #36 from Jerome C (me@jeromec.com) --- I've been watching linux-next and noticed that this commit
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/d...
was posted on linux-next back between 5.10-5.11, I don't remember but it keeps getting pushed back and not mainlined...
I think this is why the issues are still here and none of AMD are responding to this now since comment 29
