Hello,
we found a regression in 5.15.17. When iwlwifi is loaded as a module and
it cannot load a firmware it crashes:

===================================================================
Providing a firmware file (or blacklisting iwlwifi of course) fixes ist.
5.15.16 does not crash.

Can you do 'git bisect' to track down the offending commit?
And does 5.16.y work for you? How about 5.17-rc2?

I bisected it down to e23f075d77987de4215c8e0696f28bcc707506f7:
e23f075d77987de4215c8e0696f28bcc707506f7 is the first bad commit

iwlwifi: fix leaks/bad data after failed firmware load
[ Upstream commit ab07506b0454bea606095951e19e72c282bfbb42 ]
If firmware load fails after having loaded some parts of the
firmware, e.g. the IML image, then this would leak. For the
host command list we'd end up running into a WARN on the next
attempt to load another firmware image.
Fix this by calling iwl_dealloc_ucode() on failures, and make
that also clear the data so we start fresh on the next round.

I reverted this patch (and also the following one,
58d53fe49a5dfbd9204c6d605bff4c99f7549256, so the blamed patch reverted
cleanly) in 5.15.17. The general protection fault then disappeared.
I did not hat time yet to test 5.16 or 5.17-rc2.
