Your issue likely is similar to the one reported in
https://bugzilla.kernel.org/show_bug.cgi?id=215167 at least.

Please test with current kernel from unstable (6.0.6-2) or ideally
from experimental (6.1~rc3-1~exp1).

If the issue still persist, please provide kernel logs and information
specific to your hardware (in particular pci and usb devices, but best
is to reportbug to run the bug script to collect information).

Regards,
Salvatore
