Subject: 2.6.28-git: WARNING: at drivers/net/wireless/iwlwifi/iwl-sta.c:689

Hi, 

on my Thinkpad T61p I get several of the following warnings. The warning seems to happen on some reassociations 
(like after resume) but not on all. I have never seen this message with 2.6.28-rc9. Since I cannot reliably trigger 
this warning I am unable to bisect it...

Christian
