Yeah, I had similar experience with Ubuntu 8.04.
But I had Heartbeat controlling the shutdown and from within the
heartbeat init-script I called the xendomains resource script. So I
didn't have xendomains running directly at boot/shutdown.

To resolve it I had to add a sleep command in the heartbeat
init-script to make it wait for the domains to shutdown before
continuing with the Dom0 shutdown.

Which dist are you running?
