Comment 9 for bug 483483

I have the same problem on karmic and 2.6.31-17-generic. This started with the upgrade from 2.6.31-16-generic.

One other thing I noticed was that if I boot into recovery mode, the system keeps working when I plug in the usb drive and the log file looks like the attached 'works.txt'.

When booting normally, I get no errors (see attached 'hangs.txt', but the system hangs (ie. cursor freezes, cannot get to console, etc).
