Uhm. Known problem? Could you elaborate a bit? I have not seen it
before and would like to know if it is something I will encounter
regularily using ext2 and LVM.

I have run e2fsck a number of times now, and while I do not get
the kernel log message after the reboot (se below) fsck complain
and fix stuff every time in lost+found which contain a lot of
junk I cannot delete manually either.

I will try to reproduce. But trying to get as much as the (used) 
filesystem with off the disk with tar resulted in a kernel panic
(this was just after my last mail):

panic: brw_page: page not locked for IO

This was put after a couple of lines of 

Jun  5 10:04:35 firewall kernel: attempt to access beyond end of device 
Jun  5 10:04:35 firewall kernel: 08:01: rw=0, want=530420, limit=410608 
Jun  5 10:04:35 firewall kernel: dev 3a:03 blksize=1024 blocknr=622592 sector=1060832 size=4096 count=1 

on the console.
