I am either getting a lot of extra interrupts, or they are getting reported twice. This is probably not a new problem, but after switching some cards around and enabling ACPI (trying to eliminate a recurring crash, see thread "Current crash on today's kernel" for details) I am now seeing this for the first time. # vmstat -i interrupt total rate irq1: atkbd0 2 0 irq4: sio0 627 0 irq6: fdc0 10 0 irq8: rtc 763024 127 irq13: npx0 1 0 irq14: ata0 48429 8 irq15: ata1 48409 8 irq16: atapci1+ 15482279 2596 <-- should be low (<100) irq18: atapci3 4689 0 irq19: atapci4+ 3001 0 irq20: em0 15206541 2550 <-- Real source of interrupts irq21: em1 ahc0 502577 84 irq0: clk 5960581 999 Total 38020170 6377 The two marked values follow each other, with IRQ16 always 20-100 higher than IRQ20. Is this anything to worry about? The interrupt load reported by 'top' does not seem to be very high, so either the isr for IRQ16 is very cheap, or it isn't executed at all.
