There seems to be nothing wrong with these numbers. If you were suffering from an interrupt storm I would have expected much larger numbers in the "rate" column. The column "rate" shows the average number of interrupts / second. In total your system handles about 120 interrupts / second, so that shouldn't be a problem. Are you using "powerd" perhaps? Could it be that your system goes into a too deep sleep state where interrupt handling costs significantly more time? grtz, Daan
