Kickstart not rebooting on completion

[Matthew Milliss]

I'm using kickstart to install Fedora 11 and I'm having an issue with 
the system not rebooting when the install has finished. The install is 
running in text mode and it just stops on the "Running post install" 
screen. If I force a reboot the install has been successful, but I find 
myself wasting time waiting around to make sure the install has finished 
before forcing a reboot. My kickstart file is below. Any help would be 
greatly appreciated.

additions by Matt.
