Some remarks for powertop 1.2

[Thomas Meyer]

Hi.

    PowerTOP version 1.2       (C) 2007 Intel Corporation

Cn          Avg residency (10s) Long term residency avg
C0 (cpu running)        ( 0.8%)
C1                0.0ms ( 0.0%)                   0.0ms
C2                4.2ms ( 2.7%)                   1.1ms
C3               20.9ms (96.5%)                   1.8ms

Wakeups-from-idle per second :  109.0

Top causes for wakeups:
  33.2% (26.4)       <interrupt> : acpi
  14.2% (11.3)      runscript.sh : queue_delayed_work_on

   1.3% ( 1.0)              kwin : schedule_timeout (process_timeout)

I think this entry is wrong:
  10.1% ( 8.0)          modprobe : usb_hcd_poll_rh_status (rh_timer_func)

This is not modprobe! it's seems to be a general function for all hcd.
where does this info "modprobe" come from?

Why do i get so many acpi interrupts?
Any idea?
