Gentlemen,
I am running kernel 2.6.39.1 and ath9k on ath9160 radio.
The radio runs as wireless client.
It's been stable for most of the time.
But occasionally, I see error message like below. And usually after I see this message, client cannot ping AP (or at most intermittent).
"iw wlan0 link" shows it's linked.
Mar 12 18:47:33 2012 default-hostname user.err kernel:ath: txq: c970b5bc axq_qnum: 2, mac80211_qnum: 2 axq_link: c96f3b60 pending frames: 64 axq_acq
empty: 0 stopped: 0 axq_depth: 0 Attempting to restart tx logic.
Can anyone help me understand what this problem is and is there a patch available?
Thanks,
Chaoxing

Update your kernel to the latest version (or use compat-wireless), and
the problem should go away.

Below is the debugfs info when I see the log. It seems that txq gets stuck. The pending-frames stays at 124.

hey, as Felix had suggested upgrade to latest compat wireless
http://linuxwireless.org/en/users/Download#Where_to_download_bleeding_edge
install it and this message is fixed and removed by later commits
