This also happens to my friend when mounting my usb hard drive(ext3). It never failed before 11.04, and it worked on 11.04 a while ago. Looks like it has something to do with the fstab file not having a UUID for the "/" mount point, as described at http://www2b.abc.net.au/science/techtalk/newposts/795/topic795027.shtm. Somewhat geeky methods may be required to recover from a incorrectly written fstab - try it at your own risk. Marking the report as incomplete as more information may be required to narrow down the cause to this problem.
