According to the outputs that you get, that really sounds like a Hard drive which has bad blocks. Can you scan your hard drive for bad blocks using this command?
sudo badblocks -sv /dev/sda or sudo badblocks -sv /dev/hda depending if your Hard drive appears as /dev/hda or /dev/sda This will do a read-only scan of all your hard drive to find bad blocks which can be stopped anytime with CTRL+C . If you get several Exception emask error messages during the scan, most probably that you have bad blocks and that your hard drive panics/become unstable so linux kernel show outputs about it. -- Not booting after upgrade to Hardy Heron https://bugs.launchpad.net/bugs/226558 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
