I would agree, lately, I am seeing a bunch of these in my logs:

   ath: Failed to stop TX DMA in 100 msec after killing last frame

but my 802.11n 40MHz performance has been the best its been in 6 months ;-)

What's the exact error?  I've see something similar in my dmesg:

   ath: Failed to stop TX DMA in 100 msec after killing last frame

However, I get great performance regardless. Able to pull 150 mbit/s actual
in a 2x2 MIMO configuration.


Are you two using 'station' mode and associating with a OpenWRT AP. Because I'm getting abysmal performance.
Running iPerf in UDP mode, frequently gives 10% packet loss at 10 mbs...

Theplatform I'm using is pretty close to the Atheros AP83 reference design. I also have tested with a non-OpenWRT
station, and get much better performance.
