Hmm, I had been thinking of a problem with a very fast CPU.

Ok.

Also nothing special.

Ok. I guess Jordan is reading this anyway:

Please provide me with details:

1) does the system complete the final sync ?
2) does it clear the screen in preparation of a warm boot ?
3) does it require a power-off or can it be made to boot 
   by some other means (Ctl-Alt-Del) ?
4) does it always hang ?
5) do you know that the hang is not caused by some unrelated
   problem (BROKEN_KEYBOARD_RESET comes to mind :) ?
