Excuse-me my poor english, but I will try to correct...
This machine have three WiFi cards DWL-G520 (chipset Atheros, ath0, ath1
and ath2), all WiFi cards are running in hostap mode and all works fine.
One time per day happen a crash, I suspect there are any problem with
if_bridge, because all crashes I can found a backtrace related with
nve0, ath1 or ath2, all nics joint to bridge0 interface, how showed in
last crash:
kgdb kernel.debug /var/crash/vmcore.3
