** Description changed: powertop reports above 70 wakes per second in "[kernel scheduler] Load balancing tick" task, and above 200 when there's any little load, running on a Core 2 Duo processor (T6500) with a single core enabled (multicore disabled in BIOS). - Will still try disabling apic, lapic, cpu in the boot parameters and reproduce it with the mainline kernel. + Will still try noapic, nolapic, maxcpus and nosmp in the boot parameters and reproduce it with the mainline kernel.
