can't soft reboot after install

[John G Heim]

At the end of an install, my install client has a message that says 
press enter to reboot. But it doesn't work.In fact, issuing a shutdown 
command doesn't work. I've tried "shutdown -r now", "reboot". I've tried 
logging in via ssh and issuing those same commands. I have to power 
cycle the machine to get it to boot into the new install. Any ideas?
