Description Jaroslav Fojtik 2010-05-30 17:36:15 UTC
Created attachment 26586 [details]
Linux configuration file.

This bug occured for linux-2.6.32.11 and compat-wireless-2010-05-28.

I have tested repeatedly "iwconfig wlan1 up", "iwlist wlan1 scanning" and
"iwconfig wlan1 down"

Comment 2 John W. Linville 2010-06-01 18:13:34 UTC
It's not clear to me what might be at fault here.  I wonder if you can recreate this with 2.6.34?  Or 2.6.35-rc1 (or later)?
Comment 3 Jaroslav Fojtik 2010-06-02 13:12:17 UTC
Unfortunately this is double fault.

First problem is a corrupted assignment to AP inside ATH5k. I did a desperate loop that attempted to connect to AP many times.

And a second problem is a crash in a kernel.


When the first problem gets fixed, second one might be hidden.


n=1
while (( $n <= 200 ))
do
  ASOC=`iwconfig wlan1 | grep "Access Point: 00:15"`
  if [[ $ASOC == "" ]]
  then
    echo Asoc failed $n!
    ifconfig $ATH0 down
    iwconfig $ATH0 txpower 12 channel 36 essid "dvrmn.heaven-czfree.net"
    ifconfig $ATH0 up
  else
    echo Asociated - $ASOC.
    break
  fi
  n=$(( n+1 ))
done
Comment 4 Jaroslav Fojtik 2010-06-19 13:07:30 UTC
I have re-created this issue with 2.6.34 kernel and compat-wireless-2010-06-13.
So it means that this bug is still present.

Comment 5 John W. Linville 2011-01-18 19:08:08 UTC
Been awhile...are you still seeing this backtrace with 2.6.37 or later kernels?
Comment 6 Jaroslav Fojtik 2011-01-19 08:36:34 UTC
After ATH5k upgrade an association loop with 100 attempts of association is not necessary. So I do not see this crash again. Frankly the router runs without interruption so boot-up occurs only rarely.
Comment 7 John W. Linville 2011-01-19 14:51:22 UTC
Closing on basis of comment 6...
