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).
Comment 2 Stanislaw Gruszka 2013-05-02 08:44:43 UTC 
Since there is no feedback, I'll just post patch upstream.
