Hello.
I have the same problem with very fresh 15-CURRENT
(edbd489d09babebdc6c03924a912013be584c409).

The system starts OK and wifi works without problem. I can download data from
the web, surf in browser, etc. But when I try to upload something bug ( > 50
Mb), iwlwifi crashed. The easiest way to reproduce:
    cat /dev/zero | nc -v 192.168.1.xx 9999
    (with nc -v -l 9999 > /dev/null on that host)

The crash happened both in GENERIC and GENERIC-NODEBUG. I was unable to
reproduce this bug in FreeBSD-15.0-CURRENT-amd64-20240530-d2f1f71ec8c6-270474,
that snapshot seems stable.
