Deep cstate avoidance based on the number of non-idle cpus in the system does not play well with powertop! Odd. May be the dtrace probes with powertop causes all cpus to be busy at the same times?
When powertop is not running, non-idle cpu count throttling of deep c-states does not effect idle systems.
