#3 acpi creates high interrupts

[Hexchain Tong]

According to PowerTOP, the <acpi> on my Archlinux is creating too many interrupts, draining battery a lot.

Additional info:
This bug is there since I've installed Arch.
PowerTOP output:

Wakeups-from-idle per second : 10839.5 interval: 10.0s
no ACPI power usage estimate available

Top causes for wakeups:
98.2% (23534.8) [acpi] <interrupt>
0.9% (214.9) [Rescheduling interrupts] <kernel IPI>
0.3% ( 62.9) [uhci_hcd:usb3, mmc0, jmb38x_ms:slot0, firewire_ohci, nvidia]
0.2% ( 51.4) swapper/1
0.2% ( 47.7) swapper/0
0.1% ( 31.4) firefox

This also has a serious impact on some applications' performance. It costs me almost a factor of two when doing multi-precision arithmetic:
