Please do not cross-post.

The transmit queue is full; you need to understand why.  Basic info 
includes the card info (dmes|grep ath) and ifconfig output.  It usually 
helps to explain how you make your problem to occur--if you can identify 
something you are doing.  Past that there are tools in src/tools/tools 
such as ath/athstats for dumping the driver statistics.
