I've noticed something recently too - my ath device frequently stops 
working, and I get this in messages:

Jan  6 06:19:48 neutrino kernel: ath0: link state changed to DOWN
Jan  6 06:20:35 neutrino kernel: ath0: device timeout

Jan  6 06:44:10 neutrino kernel: ath0: device timeout
[and so on]


I would say this started happening for me in the last 2 weeks.

I'm running -current from Jan 4th.  All kinds of system information is here:
