Do you have network-manager installed? If you have it could cause the
problem. Init script for shutting down network-manager has higher
priority than umountnfs.sh script that unmounts network filesystems like
nfs/cifs. Solution is to not use network-manager (tested) or modify
network-manager script to require umount network filesystems before it
shuts down (not tested)
