Interrupt load appears to be rather low at only 0.4% so I'm not sure what can be causing the high count. Here is the output of vmstat. dan@home$ vmstat -i interrupt total rate irq1: atkbd0 3011 1 irq12: psm0 121265 61 irq14: ata0 58 0 irq19: uhci1+ 5181 2 irq20: fxp0 1377 0 irq22: pcm0 11 0 cpu0: timer 3812581 1923 cpu1: timer 3812247 1923 Total 7755731 3913 My kernel is pretty much GENERIC except for the removal of drivers that I don't use/need, WITNESS, and INVARIANTS.
