Attached is a dmesg from jmcnaill-pm branch: kernel GENERIC.MP (also one 
CPU core busy with interrupts). I hope someone will get some idea from 
the dmesg what I could try.

I tested the MP kernels with bge disabled from BIOS (there is a Service 
Processor attached to one port of bge and under NetBSD it is visible 
from outside only when the NetBSD doesn't touch the bge), but the 
interrupts are there in both cases. I also tried to disable USB and 
Service Processor USB devices (virtual keyboard/mouse/cd) with no success.
