Public bug reported:
The iwlwifi driver is logging microcode crashes on a daily basis. The
chip is Intel 9462 (AX201). Ubuntu release 22.04 LTS, faithfully kept up
to date.
Crash log is different from what I've found by googling, and for similar
errors the firmware version is much more recent. Here's the log output
from crash (leaving some extra lines there as well to show the chip and
firmware version):
