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 [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
