Updates crashed 3 Edubuntu desktop

[Bob Jonkman]

Unplugging everything may work because attached USB devices may be 
trying to boot.

I've got a computer on which I have to unplug external USB hard drive 
devices because the POST hangs trying to discover the external devices.  
A single USB thumbdrive has no problem, but I don't think it's a power 
problem since the external USB hard drives have external power supplies.
