Re: High interrupt count on irq12

Since I installed -CURRENT, I've noticed irq12 has a rather high
interrupt count for only 29mins of uptime. 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.

Nothing wrong with that number unless you don't use the mouse. Mice generate anywhere from dozens to hundreds of interrupts per second depending on the hardware type port settings. An hour's worth of regular desktop usage could easily generate the amount shown above.
