uc22 pc-kernel 5.15.0-30.31.1 iwlwifi Hardware error detected. Restarting.

[Paul Larson]

None of our wifi tests seem to be working on one of the amd64 systems we use for testing full disk encryption. The current kernel snap installed is:
pc-kernel 5.15.0-30.31.1 991 22/beta canonical✓ kernel

When looking through the dmesg output, I found a call trace related to iwlwifi which repeats a lot of times. I've attached a section of it as dmesg.txt, as well as dmesg output from right after a fresh boot (dmesg-boot.txt) so you can see the earlier messages, firmware loading, etc.

The relevant firmware line from dmesg is:
[ 13.667426] iwlwifi 0000:00:14.3: loaded firmware version 66.f1c864e0.0 QuZ-a0-jf-b0-66.ucode op_mode iwlmvm
