This doesn't mention SCSI anywhere.  Your problem is almost certainly a
PCI/interrupt problem.  I'm redirecting this thread to -stable.

I got panics on boot with my BP6 (SMP) when I had an ahc controller in a
PCI slot that didn't support bus mastering.  I suggest you do what the
above message says and try different combinations of cards in slots (i.e.
keep removing one until you no longer get the messages and move around
which slot is free).  This will help people track down the problem.  Also
get your mobo manual and check if any slots force interrupt sharing or
don't support bus mastering.
