That's right, interrupts!

I'm not even sure why that is such a sore subject; must have been
something before my time.

Anyway, I'm trying to hack up the sibyte watchdog driver that I wrote a
million years ago, because the 1480 has 4 timers, and the 1125 only has
2, and I'm wondering if that's causing tuxrx to reboot about 8 seconds
after I get the bash prompt (yes, it boots all the way to single user
mode now).  And yes, the original driver is highly 1250/1125 specific,
I'm glad I didn't know the 1480 had 4 timers when I wrote it.

In the original driver, the kernel requests IRQ 0 and IRQ 1 for
watchdog 0 and 1.  I have no idea where those irq numbers come from,
and I'm thinking you told me those numbers, because they aren't random,
and they do work on the SSC kernel.  So one question is: are those irq
numbers for the first 2 timers the same on the 1480?  And what are the
irq numbers for the two additional watchdog timers on the 1480?  And
how do you figure out what those numbers are, anyway?

Thanks Mr. Answerman,
