I have a new machine, I booted an SMP kernel on it and the foloowing
was the result.  

I orginally thought this panic was because of the known
interrupt-sharing issue, but after I have eliminated all the excess
on-board devices (audio, usb, etc) so that there are no shared
interrupts, I still panic when taking an interrupt right after cpu1
spins up.

I'm worried by the WARNING line for pmaptlbpl, especially since the
panic involves tlb flush.

Any suggestions?
