[Bug 145377] Re: Powertop reports huge number of wakeups and drains battery

[markusj]

Hi,

i got the same behavior with a Compal HEL80. At the beginning, i had something around 30k wakeups per second. I tweaked the system a little bit, disabled yenta, hci_usb and all pcmcia related stuff and got only a very poor improvement.
Then i tried the acpi=noirq option, with no impact. Because i read that other people had problems putting their laptop into standby with acpi=noirq, i tried it.
And, surprise: after returning from standby, powertop displayed me something between 15 and 40 wakeups per second ... nice ;)
I restarted ubuntu without the acpi=noirq option and had the same behavior again ... before standby: > 30k wups/s, after standby: something around 30.
Sometimes acpi causes ~100 wakeups, but even while typing and using an usb-mouse and an usb-keyboard, the wakeup-counter stays around 75~125 wups/s

Maybe this could help you too fix the "problem" ... and the important
question: shows your ubuntu the same behavior or am i only "lucky".

with kind regards
Markus
