I actually don't see the rtnl_lock or mutex_lock that was listed in your
original dmesg. There are a lot of warning traces from mac80211.c.

The other interesting thing is the following:

[  367.389096] wlan0: deauthenticating from 00:03:52:e3:0e:10 by local

There is another thread title "iwlagn is getting very shaky". It makes
me wonder.

Where did you get your kernel from. From you dmesg I see:

Linux version 3.1.0-rc6-gbee709a (nico@brief)

I tried to locate the SHA1 bee709a but it is not in my repository. I
want to look what the warnings from mac80211 mean.
