Summary: wakeups
Product: ACPI
Version: 2.5
Kernel Version: 2.6.32-5-686(debian), 2.6.36.2(kernel.org)
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: ACPICA-Core
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
With my new laptop a thinkpad L512 which has a Intel i915 GPU and i5 430 CPU,
I'm getting extreme high loads while idling. According to powertop the most
wakeups are:
hrtimer-start-range-ns (tick-sched-timer).
The only cure for this is to boot using: acpi=off. I already tried nolapic,
acpi=noirq and noapic, but none of them fix it.
I also tried it with and without the thinkpad_acpi module, but that did not
make any change. Tested on 2.6.32-5-686(debian) and a self tailored
2.6.36.2(kernel.org) kernel.
