Ubuntu mode hangs at "configuring network interfaces"

[Luigi Capriotti <l.capriotti@tiscali.it>]

I have been playing with debian-live since when I discovered that the 
"ubuntu mode" patches were merged:

http://lists.debian.org/debian-live/2009/04/msg00083.html

I tried to build an Ubuntu live disk using:

lh_config --mode ubuntu
lh_build

but the resulting ISO boots and hangs at "Configuring network 
interfaces...".

I wonder if anyone has faced the same issue, and what can be the root 
cause of that.

I'm using fully updated Intrepid as build host, if that matters.

Tks for any reply.
