Yes, this is still an issue. I am running Karmic amd64 on a Thinkpad X200, and had ca. 100-200 "Rescheduling Interrupts" wakeups per second. After booting with "acpi=noirq", these were reduced to ca. 10-20/s, saving me another 0.5W of power consumption.
What negative side effects should I expect from "acpi=noirq"? ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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
