Re: Assertion failure, BUG at journal.c:1732



These messages tend to indicate that the filesystem is probably
corrupted.  For some reason the kernel is triggering a BUG before
marking the filesystem as containing an error, so fsck isn't being run
on the filesystem.  If you run e2fsck on the filesystem manually,
before it is mounted (or remounted read-write, if it the root
filesystem), it should correct the problem.

I am curious what was the specific form of filesystem corruption which
was triggerring your problem.  If you could save a transcript of the
e2fsck run (say, by running it under the script program, assuming you
have a writeable filesystem available to you when you rune2fsck), I
would be much obliged.
