It seems you're right. I couldn't reproduce it again. 
May be I have missed anything. Sorry...

Yes, I have wlans_run0="wlan0" and create_args_wlan0=... in the rc.conf,
but while testing I've used `ifconfig wlan0 destroy` after `kldload if_run`.
May be it was mistyping...
Also I've noticed that messages like
"ieee80211_load_module: load the wlan_amrr module by hand for now." has
disappeared from the log. Is it normal?

So there is the one issue only: the panic if runfw.ko and wlan_amrr.ko
both loaded via loader.conf.
Have you any ideas?

Will be rev. 217511 MFC'd on the 20 january?
