I admit that memory is tight on my laptop, but it has 2 GB of RAM and everything should still work IMHO. I didn't reboot during update, I only did 'modprobe -r iwl3945; modprobe iwl3945', so there's a small chance that something went wrong during update. But I still suspect something else is wrong because I have never seen this error before. After a fresh reboot I wasn't able to reproduce the problem. But, if needed, I can do more testing later on.
