The panic doesn't seem to be related to ath(4) or do you see ath or
wlan in the backtrace?

Adrian fixed a few issues regarding stuck beacons in head, you might
wanna try this.

Also, your last post said you configured the device with
% ifconfig wlan0 create wlandev ath0 wlanmode tdma tdmaslot 0 up
This is either not the whole truth or you should definitely set a SSID
as otherwise no network will be opened.
