Comment 27 for bug 552020

I managed to reduce the Rescheduling Interrupts by appending the "nolapic" to the kernel line.

My system gets around 15 wakes per second (total!) when it's idle now, no more hundreds-of-unexplained-interrupts. Battery time and CPU temperature are back to normal, as well.

I've seen a small increment in OHCI interrupts (hda-intel, ath, sata), but it's negligible: around 40-50 wakes per second when I'm using Firefox (which makes heavy use of my HDD and wifi card). To put it in perspective, my touchpad alone will cause more than 100 wakes per second when it's active.

If someone could explain what collateral damage could "nolapic" cause, I'd be very grateful.

Otherwise, please try it for yourselves and post your results.
