I'm doing a build-of-the-world on that 1+ I mentioned earlier, and I'm
having trouble with "panic: crazy interrupts".

My disk setup is seven 80M Quantums.  One is root+swap, one is /usr,
and four more are concatenated in a ccd as /usr/src.  The seventh is
currently not used.  Console is ttya.

Initially, I would

	# cd /usr/src
	# make build > zerrs 2>&1 &
	# tail +0f zerrs

but then I would get a "crazy interrupts" crash fairly promptly.  After
three successive failures like that, I went back to what worked before,
doing

	# cd /usr/src
	# make build

However, even then I got crazy interrupts eventually.  My suspicion is
that it happens when an "esp0: ESP100 work-around activated" message
happens during the printing of something else, and running with output
going into a file and then using tail -f on the file simply makes it
more likely that something else will be printing when the esp message
prints.  Here's what the most recent crash looked like; note the
characters appearing before the "stray interrupt" messages:

At least one of the other crashes (whose output I don't have handy)
looked similar, in that I could see "esp0: ESP100..." appearing before
the "stray interrupt" messages.  (They've all been "ipl 0xc", IIRC.)

This kernel was built from the sup of Oct 25th AM.  Once this "make
build" completes, I'll bring over a fresher source tree and retry; if
anything has been done to the SPARC zs driver or the interrupt
machinery in the last week that could have fixed this, feel free to
ignore me.
