Hmm.. I just had the same problem again. I thought it was this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1021471 (fixed in 3.5.0-17.28)
Am I having the correct version installed? : 3.5.0-18-generic #29-Ubuntu SMP Fri Oct 19 10:26:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux If I need a higher version, how can I install it?
