Indeed, it wasn't set properly. I could have sworn I checked that, but
apparently not… I made an error when backporting the sysctl changes. I now get
about 60 interrupts per second when running X on irq16 (possibly vblank
interrupts for the compositor I'm running):
interrupt total rate
irq1: atkbd0 3988 3
irq9: acpi0 19361 15
irq12: psm0 123546 101
irq14: ata0 35149 28
irq15: ata1 833 0
irq16: uhci0+ 79654 65
irq20: hpet0 263768 216
irq23: uhci3 ehci1 84 0
irq256: hdac0 95 0
irq258: iwn0 67988 55
irq259: re0 35 0
Total 594501 488
