Hello; I noticed around 4,000-5,000 wakeups a second as well, not as high as
50,000, but enough to ask the question on how to lower this down, so the
processors can go into a deep sleep; try messing around with you're timer
wheel i.g. cat /proc/timer_list and cat /proc/interrupts, after tweaking my
kernel .config, and setting boot params(nolapic_timer etc..), its seems to
be around 300-400, but am still receiving wakeups here and there i.g. =
usb_hcd_poll_rh_status (rh_timer_func) and Rescheduling interrupts are too
of a couple of wakeups that I still haven't been able to honed in on.
hopefully in good timing I'll be able to quite down these timer wakeups so
the processors go to the C3 state then lower from there, in theory. (have a
look in linux-2.6.*/Documentation/kernel-parameters.txt for timer settings)
