Actually no more interrupt after I added these options back to my kernel while it's UP not SMP, and vmstat output has changed totally.

# To make an SMP kernel, the next two lines are needed
options         SMP                     # Symmetric MultiProcessor Kernel
device          apic                    # I/O APIC

IM# vmstat -i
interrupt                          total       rate
irq14: ata0                         4837          0
irq23: fxp0                      2203298         86
cpu0: timer                     50755929       1999
Total                           52964064       2086

I even don't see irq0 in vmstat at all.

Any hints?
