I took Kate off the headers.

I've verified that the interrupt that is always pending and is locking 
out the decrementer is interrupt #56, the serial port interrupt.

The serial ports are using ns16550.c, and are embedded in the "Marvell" 
GT64260 chip that you not only need
an NDA to get, but I found out today you need to go through a 
distributor first.

I checked CVS and don't see anything in the 16550 code that has 
changed.  Can anyone think of anything that might have affected this 
between 4.6 and the code in CVS?  I don't particularly want to spend 
the time going back to code that isn't under CVS control.
