Please see: https://bbs.archlinux.org/viewtopic.php?id=136607

The same error is mentioned and a patch is available. I suspect the patch has made it to the backports modules. Please do:
Code:
sudo apt-get install linux-backports-modules-cw-3.3-precise-generic
Reboot and let us see again:
Code:
dmesg | grep rt2
