Fedora 16 preupgrade problem?

[Michael D. Setzer II]

I have a test machine with Fedora 15 x86_64 and ran preupgrade 
and all seemed to go fine. But after reboot, it comes up with the 
grub menu and option to upgrade to 16, but then selecting it just 
results in a blinking cursor in the upper left. No messages on 
screen, no disk activity. 

Currently downloading DVD image, but that saying it will take 5 
hours more.
