Mattockwould 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!).Was your kernel compiled with debug info? If so, please run gdb on the ath9k.ko module and enter this: l *ath9k_tx+start+0x284 Then send me the output of that. - Felix
sure! I will do this as soon as I get to a stable connection(am remote now)so I can install gdb to gather the info for you.
