Bootloader Freezes with timer. Ok if press enter

[Francisco Reyes]

My first 6.0 machine destined for production (not to worry.. will test 
thoroughly before it goes live ;-) and it freezes on the initial boot 
screen.

If I press enter right away upon the boot menu appearing the machine boots 
fine. However, if I let the countdown start it freezes when there are 
either 8 or 7 seconds remaining (every single time). 

Any suggestions?

This was after making the machine stable as of 12-4.
Not sure if the problem existed from 6.0 Release on this machine  
since I usually press enter on the boot menu right away.
