Mandy thx for the report. Sadly those are kernels from a EOL series that
are heavily modified and thus might contain bugs that never even
occurred with a proper upstream series -- which could also be the case
due to a add-on module you use. The issue might also be fixed already.

Please retest with vanilla mainline (e.g. 7.2-rc5 or later). If it does,
please report to https://gitlab.freedesktop.org/drm/amd/-/work_items/
(ideally drop a link here afterwards; you might also search for existing
bugs there, there are a few that mention Strix Point that might match).
If the problem is not known yet, you might need to bisect this, but this
is to early to tell.

Alternatively, report the problem to the vendor of your kernel.

Ciao Thorsten
