Looks like a wlan <-> iwm module incompatibility
(some structures were changed recently).
Full kernel rebuild should fix this panic.

 It seems that it kernel panic when creating the wlan0 interface.
I guess that the modules are loaded by the loader ? (i.e. in /boot/loader.conf)

Could you test not loading them by the loader but by manually after login ?

 kldload iwmXXXXfw.ko && kldload if_iwm

 Then restart the netif service (or create the wlan0 directly).

Hi Emmanuel,

Whilst I agree the screenshot looks like the failure occurs whilst creating the
wlan0 interface, it in fact occurs when loading the if_iwm module. I have
tested by stopping the netif service and then loading the modules manually, and
you can see the screenshot here:

I never got a chance to restart netif service.
