That's a bit unfortunate ... it shows that the domain validation code
negotiated identical settings in the old kernel, so it doesn't look like
that's the problem.
My best guess would be that the bus is slightly marginal. The aic7xxx
drivers are notoriously sensitive to bus problems. Could you try
lowering the bus speed to 10MHz in the aic7xxx bios and see if that
helps?
Thanks,
James
