FreeBSD-head r217622, i386 eeepc of some description
Monitor mode with if_ath on at least the AR9280 is broken. It hasn't been tried on earlier cards.
After a short period, frames stop being received.
# ifconfig wlan0 create wlandev ath0 wlanmode monitor
# ifconfig wlan0 channel 6
# ifconfig wlan0 up
# tcpdump -ni wlan0 -y IEEE802_11_RADIO
[wait a short period]
Sometimes bouncing the interface is enough. Other times unloading/reloading the interface is enough.
