Using powertop I can see more than 100K wakeups/s (extra_timer_interrupt is first on the list but I think it's irrelevant since it only shows about 100 wakeups), and the CPU is not going into C2 mode at all. Strangely however the cpu is 99% idle, and top doesn't show "system" or "user" cpu usage.
This sounds bad. Let me get this straight. "Wakeups-from-idle per second" shows 100 000, but no large numbers show up under "Top causes for wakeups"? Can you post the contents of your /proc/interrupts and /proc/timer_stats twice, taken within a few seconds difference? Marti
