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? -- Alexander Zagrebin
