John, what extra hardware do you have in your A4000? From what I can see it
is just the CSPPC board (although you said CSMk3 before) and an A4066
ethernet card?
(BTW, I wonder why your CSPPC has no serial number.)

So the most important difference between our systems is A3000-SCSI on one
and IDE on the other side. Maybe you want to configure a test kernel
without wdc, even if your A1200 seemed to work with it...

And while you're at it, building a new kernel, you could also enable some
debugging options, like DEBUG, DEBUG_PAGE0 and DEBUG_KERNEL_START.

How much memory do you have installed? Did you already run a memory test?

Hmm. That would be strange, as we are both running the same 68060 board.
