 Thanks for the input, Dave.  I've seen your name here and other places, and
 respect your opinion.
 One of the people that was having the lockup problem, used a program that
 turns off the 16550 fifo.  This cleared up the lockup problem.

 Now I know the beast, and I know the antidote.  The problem is that I think
 it's unprofessional to distribute a program which requires someone else's
 program to make it function properly.

 I know that if anyone knows what to do, you should.
 How do I go about Detecting/Disabling (More important) 16550 FIFOs
