This is what I get:: cat /proc/acpi/processor/CPU1/info processor id: 0 acpi id: 1 bus mastering control: no power management: no throttling control: no limit interface: no cat /proc/acpi/processor/CPU1/power active state: C0 max_cstate: C8 bus master activity: 00000000 maximum allowed latency: 2000 usec states: "dmesg | grep -i power" also gives nothing. I have ACPI enabled in BIOS and in kernel I have these set ("grep -i acpi .config | grep =y"): CONFIG_ACPI=y CONFIG_ACPI_PROCESSOR=y CONFIG_ACPI_THERMAL=y CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_SYSTEM=y CONFIG_X86_ACPI_CPUFREQ=y CONFIG_PNPACPI=y CONFIG_SATA_ACPI=y I'm probably missing something crucial here. So how do I enable power states? I'm using 64-bit Gentoo. My mobo is Asus P5B Deluxe. Otherwise ACPI works fine. _________________________________________________________________ FREE pop-up blocking with the new MSN Toolbar - get it now! http://toolbar.msn.click-url.com/go/onm00200415ave/direct/01/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
