Well, I got around the problem by turning off the NMI_watchdog, which can be
done at the LILO: prompt by adding nmi_watchdog=0. The system boots and the
volumes on the 3ware cards are available.  For some reason the latest 3ware
drivers (>1.02.00.006) trick the watchdog into thinking that the CPU has
locked up dropping me into kdb, when in fact it hasn't.  I don't know if
this is a bug in the 3ware driver or the nmi_watchdog.

Uh, duh, yocum.  Make sure you compile the base SCSI into the kernel as well
- then I had no problem.  ;-)
