Alexey, > Most probably, you have ACPI disabled either in the BIOS or in the > kernel (command line or compiled out). Please check if it is enabled. I seem to have ACPI enabled in the kernel: # grep ACPI /boot/config-2.6.32.10-custom CONFIG_X86_64_ACPI_NUMA=y # Power management and ACPI options CONFIG_ACPI=y CONFIG_ACPI_SLEEP=y CONFIG_ACPI_PROCFS=y CONFIG_ACPI_PROCFS_POWER=y # CONFIG_ACPI_POWER_METER is not set CONFIG_ACPI_SYSFS_POWER=y CONFIG_ACPI_PROC_EVENT=y CONFIG_ACPI_AC=y CONFIG_ACPI_BATTERY=y CONFIG_ACPI_BUTTON=y CONFIG_ACPI_VIDEO=m CONFIG_ACPI_FAN=y CONFIG_ACPI_DOCK=y CONFIG_ACPI_PROCESSOR=y CONFIG_ACPI_HOTPLUG_CPU=y # CONFIG_ACPI_PROCESSOR_AGGREGATOR is not set CONFIG_ACPI_THERMAL=y CONFIG_ACPI_NUMA=y CONFIG_ACPI_CUSTOM_DSDT_FILE="" # CONFIG_ACPI_CUSTOM_DSDT is not set CONFIG_ACPI_BLACKLIST_YEAR=0 CONFIG_ACPI_DEBUG=y # CONFIG_ACPI_DEBUG_FUNC_TRACE is not set CONFIG_ACPI_PCI_SLOT=y CONFIG_ACPI_CONTAINER=y CONFIG_ACPI_SBS=y CONFIG_X86_ACPI_CPUFREQ=y CONFIG_HOTPLUG_PCI_ACPI=m CONFIG_HOTPLUG_PCI_ACPI_IBM=m CONFIG_PNPACPI=y CONFIG_ATA_ACPI=y CONFIG_PATA_ACPI=y # ACPI drivers # ACPI drivers CONFIG_THINKPAD_ACPI=m CONFIG_THINKPAD_ACPI_DEBUGFACILITIES=y # CONFIG_THINKPAD_ACPI_DEBUG is not set # CONFIG_THINKPAD_ACPI_UNSAFE_LEDS is not set CONFIG_THINKPAD_ACPI_VIDEO=y CONFIG_THINKPAD_ACPI_HOTKEY_POLL=y CONFIG_ACPI_WMI=y # CONFIG_ACPI_ASUS is not set CONFIG_ACPI_TOSHIBA=m but, interestingly, the ACPI states are not listed in /proc/acpi/info: # cat /proc/acpi/info version: 20090903 what could be wrong? dmesg does report ACPI messages: # dmesg | grep ACPI [ 0.000000] BIOS-e820: 00000000bf75c000 - 00000000bf7bf000 (ACPI NVS) [ 0.000000] BIOS-e820: 00000000bf7e4000 - 00000000bf7ff000 (ACPI data) [ 0.000000] modified: 00000000bf75c000 - 00000000bf7bf000 (ACPI NVS) [ 0.000000] modified: 00000000bf7e4000 - 00000000bf7ff000 (ACPI data) [ 0.000000] ACPI: RSDP 00000000000fe020 00024 (v02 HP ) [ 0.000000] ACPI: XSDT 00000000bf7fe120 0009C (v01 HPQOEM SLIC-MPC 00000001 01000013) [ 0.000000] ACPI: FACP 00000000bf7fc000 000F4 (v04 HP SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: DSDT 00000000bf7ee000 0ABEA (v02 HP SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: FACS 00000000bf76e000 00040 [ 0.000000] ACPI: ASF! 00000000bf7fd000 000A5 (v32 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: HPET 00000000bf7fb000 00038 (v01 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: APIC 00000000bf7fa000 0008C (v02 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: MCFG 00000000bf7f9000 0003C (v01 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: SLIC 00000000bf7ed000 00176 (v01 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: SSDT 00000000bf7ec000 0073D (v01 TrmRef PtidDevc 00001000 INTL 20051117) [ 0.000000] ACPI: SSDT 00000000bf7eb000 00172 (v01 VaRef Va_Acpi 00003000 INTL 20051117) [ 0.000000] ACPI: BOOT 00000000bf7ea000 00028 (v01 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: SSDT 00000000bf7e9000 00C39 (v01 INTEL SataPri 00001000 INTL 20051117) [ 0.000000] ACPI: SSDT 00000000bf7e8000 006C5 (v01 INTEL SataSec 00001000 INTL 20051117) [ 0.000000] ACPI: SPCR 00000000bf7e7000 00050 (v01 HPQOEM SLIC-MPC 00000000 MSFT 01000013) [ 0.000000] ACPI: ASPT 00000000bf7e6000 00034 (v04 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: WDAT 00000000bf7e5000 00224 (v01 HPQOEM SLIC-MPC 00000001 MSFT 01000013) [ 0.000000] ACPI: SSDT 00000000bf7e4000 009F1 (v01 PmRef CpuPm 00003000 INTL 20051117) [ 0.000000] ACPI: Local APIC address 0xfee00000 [ 0.000000] ACPI: PM-Timer IO Port: 0x408 [ 0.000000] ACPI: Local APIC address 0xfee00000 [ 0.000000] ACPI: LAPIC (acpi_id[0x01] lapic_id[0x00] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x02] lapic_id[0x02] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x03] lapic_id[0x04] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x04] lapic_id[0x06] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x05] lapic_id[0x01] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x06] lapic_id[0x03] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x07] lapic_id[0x05] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x08] lapic_id[0x07] enabled) [ 0.000000] ACPI: IOAPIC (id[0x02] address[0xfec00000] gsi_base[0]) [ 0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl) [ 0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 high level) [ 0.000000] ACPI: IRQ0 used by override.
