Hmmm, sorry to follow myself up, but . . .

Yes, the bootloader will load a kernel from the ARCIN interface via
UNIXFS, but it then panics in exactly the same way as it did with the
Conner drive attached - waiting for irq.

However, if the same kernel is loaded from an ADFS device, it runs
fine and the IBM drive attached to the ARCIN can be accessed perfectly
well - even via PCNFS.

Have you managed to boot the kernel off an ARCIN-connected drive and,
if so, are any of the changes you've made in current likely to
be related to this?
