Hi, there is a way to crash a connected wireless box running with ath(4) by using another one with an ath(4) interface in hostap mode. Steps to reproduce: # ifconfig ath0 powersavesleep 0 # ping <wireless-client-ip> The panic is in: ath_beacon_config() Problem: Fatal trap 18: integer divide fault while in kernel mode on the wireless client uname shows: FreeBSD 5.3-STABLE FreeBSD 5.3-STABLE #0: Sat Jan 29 19:30:55 CET 2005 i386 Martin
