Nope; still panicing with a uniprocessor kernel. I was getting some odd
errors from one of the drives so I swapped it for another drive of the
same type. Still no joy.

I can build a debugging kernel if anyone wants me to.

I'm considering trying different motherboards (we've got plenty of other
machines with the same boards/CPUs), although I've got another dual
PII/350 (same board and one IBM disk) on 4.3-RELEASE/SMP kernel which is
rock solid. Is this newfs problem characteristic of hardware trouble?

Cheers,
