--- Comment #1 from Bjoern A. Zeeb <bz@FreeBSD.org> ---
I assume with firmware you mean a firmware crash?

For iwlwifi suspend/resume is not fully implemented but the chipset should come
back.  You have to down the interface before suspending.  See
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263632

One thing you could try is:
go to console ( Ctrl-Alt-F1 )
load the driver
if you create a wlan0 interface, ifconfig wlan0 down (in first instance; if
that works, leave it running in a second attempt maybe):
devctl suspend iwlwifi0
devctl resume iwlwifi0

That doesn't do a full system suspend but might reveal what you are hitting.
