I'll have to see if I can reproduce this; never seen it. It is very
strange that there are no beacon frames and no traffic is being rx'd or
tx'd. This would seem to indicate interrupts have totally stopped
(athdebug intr should show interrupts at least for the periodic events).
There should be some activitiy and/or error counters should show some
problem. At the very least tx traffic should either fill up the
available hardware tx descriptors (in which case ifconfig would show the
interface marked OACTIVE) or you should get errors.
Presumably you've tried different cards and/or hosts? Does this happen
on all your ap's or just one?
