Created attachment 714370 [details] ath5k_fix_tx_complete_work_reschedule.patch This is proposed fix for the problem. I started kernel build with the patch here: http://koji.fedoraproject.org/koji/taskinfo?taskID=5155622 Please test it. If problem is not reproducible, please test if the patch does not cause any other problems (regressions).
Since there is no feedback, I'll just post patch upstream.
