Bug Description

After upgrading the kernel to newest official supported kernel version, it caused a bug. I upgraded the system with "sudo apt update && sudo apt full-upgrade".

Everytime the desktop PC boots, it prints out the following errors before the Ubuntu GUI loaded completely.

I also see these warning messages if I select a kernel newer than 5.15.0-33-generic.
Kernels 5.15.0-39-generic and 5.15.0-41-generic both display the warning messages.
The PC still boots normally and there doesn't seem to be any adverse performance.
Ubuntu 22.04 fully up-to-date
