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 PS: I'm using the "stock" kernel: 2.6.24-17-generic #1 SMP Thu May 1 14:31:33 UTC 2008 i686 GNU/Linux -- Powertop reports huge number of wakeups and drains battery https://bugs.launchpad.net/bugs/145377 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
