Subject: e2fsck doesn't finish

Hi all,

I'm running into an e2fsck issue which seems to occur with one
particular filesystem. The version from Ubuntu, Fedora and the latest
release compiled from source all exhibit the same issue.

On one filesystem I have, when I run e2fsck, it prints it's doing step 1
and then after a while just:
"e2fsck: aborted"
Nothing else is printed. I tried a badblock scan on the partition, but
that didn't reveal any badblocks.

Here is the output of dumpe2fs:
https://schwart6.home.xs4all.nl/dumpe2fs.sda4.gz

I suspect there's some condition with that filesystem that e2fsck
doesn't handle. What would be the best way to figure out more about this
problem?

Best regards,
Julius
