I'm having this problem after installing the 2.6.24.1-26.fc9 kernel.
Attempting to run debugfs on either /dev/sda2
or /dev/VolGroup00/LogVol01 gives me a message about a bad magic number
in the superblock, so I've been reluctant to go further.  However, if
you think it would be helpful, Eric, I'll do it.  It is, after all, just
a VM.
