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"?
