[Bug 641741] [NEW] EXT4-fs crash on boot attempting to fix minor corruption

[Owen]

Public bug reported:

Forced to hard reset by a strange system lockup, resulting in corruption of my ext4 root partition.
System would crash on boot, any attempt to mount or fix the file system using the recover boot menu option or the 10.04.1 livecd also crashed.
Eventually got a SystemRescueCd linux cd to boot and ran fsck which fixed the corruption in a matter of seconds and was able to boot ubuntu again with no problems, no freezing or fs corruption since.

See this thread for the whole saga:
http://ubuntuforums.org/showthread.php?t=1563529

There is a screenshot of the crash when attempting to boot from the
livecd in the above thread.
