--- Comment #1 from The Linux kernel's regression tracker (Thorsten Leemhuis) ([email protected]) --- Could you bisect, as explained by
https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html ?
This most likely will be needed to find the people that can handle this and
verify that this is a upstream problem, too (as you afaics seem to be using a
vendor kernel).
