You probably copied the devices from a host with a slightly
different architecture or device numbering. You must delete
the /dev/ and /devices/ directories and the /etc/path_to_inst
file and copy that from the new machine while booted from
a live-CD, see the relevant section in my original clone script:
# delete source machines devices and copy devs
# generated from live DVD below present devs
# This works over different hardware
mount -F lofs -o nosub / /mnt
rm -rf dev devices
(cd /mnt;tar cvf - devices dev)|tar xf -
cp /etc/path_to_inst etc/
