Here it is:
root at cubie:~ # vmstat -i
interrupt                          total       rate
irq0: ipi                          10968         15
irq3: ipi                            293          0
irq6: ipi                            786          1
irq33: uart0                         217          0
irq54: a10_timer0                   1629          2
irq71: ehci0                        5791          8
