Tomasz, In the idle scenario you described, offline cpus will consume more power than on-line CPUs which are permitted to naturally enter idle.
That is becausee Linux today doesn't put offline CPUS into deep power saving C-state: http://bugzilla.kernel.org/show_bug.cgi?id=5471 cheers, -Len ps. you might consider suspending the system and waking with the RTC if you just want to run a backup in the middle of the night. _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
