Hello,

I have Freescale 1020 WLAN board with two Atheros AR9390 wlan cards. 
Board comes with Atheros binary which works quite well but I need to do 
some changes for our product so I decided to try with ath9k. I managed 
to compile and load all the modules in a board and I am getting two wlan 
interfaces.
First I decided use them as an station and associated to accesspoint. 
First basic test is just ping the accesspoint from board and that causes 
following problem.

ath: txq: ef9797dc axq_qnum: 2, mac80211_qnum: 2 axq_link: (null) pending frames: 124 axq_acq empty: 0 stopped: 1 axq_depth: 0  Attempting to restart tx logic.
ath: txq: ef9797dc axq_qnum: 2, mac80211_qnum: 2 axq_link: (null) pending frames: 124 axq_acq empty: 0 stopped: 1 axq_depth: 0  Attempting to restart tx logic.

... And this error continues as long as I shutdown the board.


This happens just after three successful ping packets.  Any idea?

I am using latest stable compat-wireless-2.6.39-rc1-3.tar.bz2 packet. I 
tried to use bleeding edge packet but I could not load ath9k.ko module.
And linux kernel is 2.6.32.

Yours,
