I had this for a while. Lets take a look at what is happening:

>From /etc/init.d/networking:


            echo -n "Deconfiguring network interfaces: "
            ifdown -a
	    echo "done."

              system has.

              Current state of network interfaces.

In my case, there were interfaces that were not up that ifstate said
were up. Why? Because /etc/rcS.d/S39ifupdown was causing a
segmentation fault. Why? Because I had compiled a newer version of
libstdc++ when using the potato distribution and after upgrading to
woody, applications were using the one I compiled in /usr/local and
not the one that came with woody. Deleting my library in /usr/local/
most likely cured it although I recall writing a script to do the

As a quick work-around, try wiping out /etc/network/ifstate and see if
you continue to have the problem (echo -n > /etc/network/ifstate)
right before shutting down. If that works, you might want to add that
to /etc/init.d/networking right before the "ifdown -a" part mentioned
