Public bug reported:
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
** Affects: snapd (Ubuntu)
Importance: Undecided
Status: New
** Attachment added: "dmesg.txt"
