Has anyone opened a pr(1)?
At least that way, it would be recorded as a problem.

$ grep kld_list /etc/defaults/rc.conf
#kld_list=""# Kernel modules to load after local disks are mounted

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.

Br,

Tommi

if_iwm crashes kernel when loaded from /boot/loader.conf

2017-04-07 Thread Tomasz CEDRO
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.
