I just had another core dump on 9.2-PRERELEASE #1 r255487 amd64, and I
think i see a pattern. Every now and then, at least once per day, my
Atheros AR9285 hangs. Ifconfig shows it as associated, it does not loose
IP adress, i can ping 127.0.0.1 but nothing else. As it happens quite
often, I made an alias for it in .tcshrc:

sudo ifconfig wlan0 destroy && sleep 3 && sudo ifconfig wlan0 create wlandev ath0

If virtualbox is running with guest with bridged adapter my system crashes:

kaa.mimar.rs dumped core - see /var/crash/vmcore.3
