Okay but on Asus X61S idle fallbacks to cpuidle: intel_idle: MWAIT substates: 0x3122220 intel_idle: does not run on family 6 model 23 so forcing max_cstate to 0 will turn off the cpuidle on those machines too? -- Pardus Linux http://www.pardus.org.tr/eng -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
