Sadly just a "me too" - many ath0: device timeout (txq 1, txintrperiod
2) (period in range 1-3), and no wireless connection. This is with
a pci card which also has an Atheros (0x168c) 5212 (0x0013).

I note the man page says:

     ath%d: device timeout  A frame dispatched to the hardware for
     transmission did not complete in time.  The driver will reset the
     hardware and continue.  This should not happen.
 
which doesn't fill one with hope.
