Comment:
In another uncontrolled and non-rigorous test, I ran PowerTOP on a Dell XPS 15 9575 laptop with the stock configuration (PREEMPT and HZ=1000) and never saw fewer than 700 wakeups per second when doing nothing else on the system. With PREEMPT_VOLUNTARY and HZ=250, the same idle observation generally stays below 700 wakeups per second, and sometimes falls as low as 400/sec.
