It's probably DNS getting stuck in this case.  In an ideal world,  
you'd only run ntpdate if the system had an IP address and could  
verify connectivity to it's DNS servers.

One option could be to remove ntpdate from the init scripts and run it  
as part of the "up" scripts as defined in /etc/network/interfaces - on  
the assumption that having configured the network means you'll have a  
DNS server to talk to.
