Doh! Please don't re-install from scratch until you report something in :)

This sounds like a kernel panic, and we'll need to see if we can find 
what the error is exactly. For future reference, the way to do this is such:

* Start install
* Switch to "console" with Ctrl-Alt-F1

Monitor the console for any kernel messages. When the kernel panics, it 
should give you 15 seconds to press a key to pause the auto-reboot. If 
you can, take a pic of the panic message, or send the details over by 
transcribing them. That'll let us figure out if its a driver bug, kernel 
bug, etc.
