Hmmm...  I haven't seen that one except when I try to shut down (after
shutdown, it'll sometimes get a decrement exception and almost get back
to DINK--this hasn't been high on my priority list for obvious reasons ;-).

That's fine, but somewhat confusing.  I set up a two-level interrupt
structure.  com1 uses ISA irq4 while fxp is using EPIC irq 4.  All of
the ISA interrupts are going into another EPIC irq.
