I'm having a problem with ACPI on an Atom N455-based netbook (Samsung N143-DP05UA to be precise). Right after I start the laptop I only see one supported power state: # sysctl dev.cpu.0.cx_supported dev.cpu.0.cx_supported: C1/1 But after 4+ minutes of uptime more power states kick in: # sysctl dev.cpu.0.cx_supported dev.cpu.0.cx_supported: C1/1 C2/20 C3/100 I'd like to have all Cx right after the boot. Is this possible? (The temporary solution I employ is to update hw.acpi.cpu.cx_lowest every time devd gets ACPI CMBAT message; this appears to happen right after cx_supported is updated). Also, when I boot the same machine under Linux (latest Ubuntu), powertop reports C1, C2 and C4 right away. Is it possible to get C4 under FreeBSD as well? Other ACPI problems, which I have are: 1. When the power cord is plugged in, C3 state disappears. 2. When I plug (or unplug) the power cord I get these two messages: ACPI Error: [\\_SB_.VDRV] Namespace lookup failure, AE_NOT_FOUND (20101013/psargs-464) ACPI Error: Method parse/execution failed [\\_SB_.PCI0.LPC0.H_EC._Q51] (Node 0xc42ac1e0), AE_NOT_FOUND (20101013/psparse-633) (This appears to be harmless). My verbose dmesg is at [1], ASL dump is at [2], loader.conf is: kern.hz=100 hint.p4tcc.0.disabled=1 hint.acpi_throttle.0.disabled=1 hw.pci.do_power_nodriver=3 hint.apic.0.clock=0 hint.atrtc.0.clock=0 And sysctl hw.acpi output is: hw.acpi.supported_sleep_state: S3 S4 S5 hw.acpi.power_button_state: S5 hw.acpi.sleep_button_state: S3 hw.acpi.lid_switch_state: NONE hw.acpi.standby_state: NONE hw.acpi.suspend_state: S3 hw.acpi.sleep_delay: 1 hw.acpi.s4bios: 0 hw.acpi.verbose: 0 hw.acpi.disable_on_reboot: 0 hw.acpi.handle_reboot: 1 hw.acpi.reset_video: 0 hw.acpi.cpu.cx_lowest: C3 hw.acpi.acline: 0 hw.acpi.thermal.min_runtime: 0 hw.acpi.thermal.polling_rate: 10 hw.acpi.thermal.user_override: 0 hw.acpi.thermal.tz0.temperature: 54.0C hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.passive_cooling: 1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: 90.0C hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 98.0C hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 hw.acpi.thermal.tz0._TC1: 0 hw.acpi.thermal.tz0._TC2: 10 hw.acpi.thermal.tz0._TSP: 2 hw.acpi.battery.life: 46 hw.acpi.battery.time: 194 hw.acpi.battery.state: 1 hw.acpi.battery.units: 1 hw.acpi.battery.info_expire: 5 PS.
