OK, here it is:

interrupt                          total       rate
irq1: atkbd0                           2          0
irq6: fdc0                            10          0
irq8: rtc                        1140653        127
irq13: npx0                            1          0
irq16: atapci0                    129099         14
irq21: rl0                        345707         38
irq24: fwohci0                         1          0
irq28: sym0                           30          0
irq29: sym1                           30          0
irq31: fxp0                       140237         15
irq0: clk                        4456164        499
Total                            6211934        696

This is after 2.5 hours uptime.

Thanks,
