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). ** Attachment added: "works.txt" http://launchpadlibrarian.net/38634508/works.txt -- System freezes after plugging in a usb flash drive https://bugs.launchpad.net/bugs/483483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
