freebsd stable - Apr 2017 - if_iwm crashes kernel when loaded from /boot/loader.conf

Hello,

I noticed a problem when loading if_iwm from /boot/loader.conf kernel
crashes as it cannot load module firmware dead loop occurs. Adding
iwm8000Cfw before if_iwm does not help.

Loading if_iwm on a running system works fine and gives operational wifi.

Intel Corporation Wireless 8260 class=0x028000 card=0x10108086
chip=0x24f38086 rev=0x3a hdr=0x00

This has been happening to my Intel 8260 as well.
It seems to be a known bug.

I circumvent it by manually loading the wifi modules after boot. This
doesn't crash the system.

As a dirty hack? You could add the loading as a script and automatically
load the modules when the FreeBSD is fully up and running.
