Thanks. Seems we have advanced!
But unfortunately, it seems to be somehow racy on initialization.
Tried both
stable/13 at git 44c69c0a3172b1af1211d7afd72d68deca1099b2 with
cherry-picking git 170acccf1e191ae28571845ad6f0b5a2fbf0effc
and
main at git fcaf016796cc0272a8c239850fa87244eebefe13, which is after
git 170acccf1e191ae28571845ad6f0b5a2fbf0effc.
each of which has devmatch_blacklist="if_iwm.ko" in /etc/rc.conf.
*Maybe devmatch_blacklist="${devmatch_blacklist} if_iwm.ko"
would be safer.
Sometimes fairly initialized and associated, but sometime not,
regardless cold boot or warm restart.
Switching to wired (em0) connection and back to wlan0 (iwlwifi0)
sometimes work but sometime not (firmware crash just as before).
Thanks in advance!
