From: Aaro Koskinen <aaro.koskinen@xxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit c796d1d97c3035cf54d4d5a9e75abd094db80e76 upstream. Limit idle ticks to total ticks. This prevents the annoying rackmeter leds fully ON / OFF blinking state that happens on fully idling G5 Xserve systems.
