system freezes when using wireless network

Hi all,

I use Arch on a Thinkpad T420 and I have the following problem. Whenever using the wireless, the system freezes. The wireless seems to work fine, up to the point when my system hangs. The freezes are random, but typically my system does not run for more than 1h without crashing. I managed to track the problem in the logfiles (in kernel.log) and i see:

The system is up to date (kernel 3.2.1 and networkmanager 0.9.2.0). Any help is appreciated. Thanks!
