It appeard that a filesystem error caused the panic when mounting one 
of the LVs. A fsck on a newly booted system cured that problem.

Furhtermore the oops happening after doing some work (eg. compiling) 
while the LV in question was mounted, but working on a different 
filesystem, also seems to have dissappeard. However, doing some work on 
the filesystem of the LV in question (from simple ls, to compilations) 
brings back the oops. I'm unable to umount the filesystem and 
eventually everything hangs.

What could be wrong?
