Hi, I've noticed that there a quite a few users reporting excessive amounts of "Rescheduling Interrupts" from multi core machines, and it seems concerting that the scheduler is pulling the processors out of C3 states rather a lot. In some cases, there are reports of >10,000 Rescheduling Interrupts a second, which seems excessive.
The following rune apparently should help, but it does not make (much) of a significant change: echo 1 > /sys/devices/system/cpu/sched_mc_power_savings apparently this should reduce the number of cross-CPU wakeups on near-idle systems. Since it may be draining excessive amounts of power are there ideas if this a scheduling problem and how to resolve this?
