Is there something wrong with doing 
while true; do dd if=/dev/zero of=/dev/vg1/test; done
and
lvextend -L+90M /dev/vg1/test

at the same time?

It caused a system hang (no messages, no log) on linux-2.4.0-test12-pre3
(with ext2 online resize patches, but there obviously was no filesystem 
on the volume)

Jan


PS: Andreas, perhaps the errors I saw were not ext2 related. Maybe the 
kernel doesn't like writing to the device and resizing it at the same time?
