Note that you need to apply the VFS-lock patch AFTER the lvm-1.0.1 upgrade
patch, otherwise that patch will reverse the VFS-lock patch!

You should try ext3 from 2.4.18, or get it from the ext3 CVS (at
cvs.gkernel.sourceforge.net:/cvsroot/gkernel ext3).  It has fixes
for a number of problems caused by error conditions while running.
If there is still a problem with ext3 oopsing with a full snapshot
(which is essentially an oops because of an I/O error on the disk)
then please file a separate bug report to the ext3 developers
(ext2-devel at lists.sourceforge.net).

Cheers, Andreas
