Thanks for your reply (and sorry for apparrently submitting my mail
multiple times - the crashed machine is also the mail relay and had some
trouble).

Right... it's 2.6.32-5-amd64 (the debian squeeze kernel), and it is indeed a
loopback device.

It's normally mounted like this:

   mount -orelatime,biosize=28,logbufs=8,logbsize=256k,allocsize=8k,inode64,largeio ...

There are five logical volumes on this machine which are mounted via
loopback device, all XFS. The other ones seem to work fine.

I hope not :) I can mount the volume read-only, and apparently read a lot
of files on it. My main problem seems to be the crashing xfs_repair.
