OK - thanks I will try this and rerun my tests.

What I have found though is that the LVM_VFS_ENHANCEMENT in lvm.c gets 
removed with the lvm-1.0.1 upgrade patch.  Is this the way it is supose to 
be? Isn't LVM_VFS_ENHANCEMENT needed anymore?

Let me see if I understand this correctly:
The problem of the kernel Oops when a snapshot overflows is actually a 
filesystem maintainer's/developer's problem because.  The reason is that when 
a snapshot overflows it generates a disk full and it is up to the filesystem 
to deal with that and pass that error up the stack?

Therefore, if there was an Oops on an:
* ext3 snapshot I would have to tell the ext3 developer's/maintainer's
* resierfs snapshot I would have to tell the resierfs developer's/maintainer's
* xfs snapshot I would have to tell the xfs developer's/maintainer's

All I'm trying to do here is understand this a little more so that I can 
follow up with the correct people about these problems.

Thanks Andreas for your time.
