Hello!

Thank you for a fast response. I've switched my kernel to zen-sources one  
with this patch applied - yep - it helped. Module does not oop anymore.
But with this update (moslty from 2.6.24 do anything else) i've lost  
ability to connect with my home WPA network..
I've managed to do this only twice with plenty of tries and hours of  
waiting ;/

After second time connection dropped 3 minutes later with

May 27 23:52:26 thinkpad kernel: [  936.601464] iwl4965: Error sending  
REPLY_RXON: time out after 500ms.
May 27 23:52:26 thinkpad kernel: [  936.601477] iwl4965: Error clearing  
ASSOC_MSK on current configuration (-110).

and some seconds after

May 27 23:53:28 thinkpad kernel: [  999.187037] wlan0:  
deauthenticate(reason=3)
May 27 23:53:28 thinkpad kernel: [  999.187320] iwl4965: Microcode SW  
error detected.  Restarting 0x82000000.

In an attachmenet there is log from one of a tries.

My enviroment:

router: Linksys WRT54GP2
 \_ WPA - PSK - TKIP
 \_ network type Mixed (B and G)
 \_ ssid broadcast on
 \_ Preamble type: Long [ but in logs it switches to short one?]
 \_ Beacon every 1000 ms
 \_ other options keep untouched.

client: ubuntu 8.04
  \_ custom kernel Linux thinkpad 2.6.26-rc4-zen0 #2 SMP Tue May 27  
22:22:44 CEST 2008 i686 GNU/Linux
  	\_ made from git -  
http://zen-sources.org/cgi-bin/gitweb.cgi?p=kernel.git;a=summary - it have  
latest iwlwifi brnach merged
   \_ Intel 4965AGN card - driver version 1.2.26ks

Problem is - I can't associate with my AP. Whatever I try, it always  
disconnect just after "Group rekeying completed" using plain  
wpa_supplicant.
With network manager it is authenticated/deauthenticated monologue..

ex:

till infinity...
Sometimes it connects, works fine up to key change (3600 s) and then log  
looks like this above.

I have issues like this only on iwl driver. The same computer, the same  
hardware works fine under windows xp. Also broadcom laptop works fine too  
with this AP. Even my windows mobile 6 device works like a charm so it is  
not a linksys issue.
My previus laptop have intel 3956 card. On IPW driver it worked well, but  
on IWL one - it was completely broken.

My determination made me write here, becouse have no chance to solve it  
myself - it looks like driver bug. Aftr using PLENTY of versions - from  
1.2.0 up to latest GIT one you are my last chance. Would REALLY appreciate  
your help. Of course I can provide as much debug info as you want.

Best regards,
Bartek
