I see ath9k in the image, but am unsure if its related.
kernel is: 3.3.0-rc7-next-20120316

this looks like some new issue in ath9k, lets try to recreate it here

would be nice to recreate, then bisecting will be more accurate to do.. I am trying userspace tweaks here and there but no luck(hostapd etc..) keep in mind this is for the RX DMA, the above just occured..
as for writing a small app I still need to try, but my C skills only go so far(anything to trigger!).
