grumpybozo:

I occasionally get this same hang (same line number cited) on a Buffalo WZR-HP-G300NH (also an ath9k device.)

After a burst of these warnings, wireless is flaky (lots of pauses and disconnects) and occasional "ath: phy0: DMA failed to stop in 10 ms" warnings are logged. If I use the /sbin/wifi tool to down+up the wifi, it's good for as short as a few days or as long as a few weeks. Seems like a bug in the ath9k driver or hardware.
