Hi. On my machine (Sony PCG-C1VSX/K notebook), Lid open/close (or, acpiconf -s 1) output following messages /boot/kernel/kernel: acpi_lid0: Lid closed /boot/kernel/kernel: acpi0: AcpiHwObtainSleepTypeRegisterData failed - AE_NOT_FOUND /boot/kernel/kernel: acpi_lid0: Lid opened /boot/kernel/kernel: acpi0: AcpiHwObtainSleepTypeRegisterData failed - AE_NOT_FOUND What these message mean? acpi sleep doesn't work? ACPI related dmessage is as follows acpi0: <SONY P1 > on motherboard acpi_cpu0: <CPU> on acpi0 acpi_cpu: CLK_VAL field overflows P_CNT register acpi_cpu: CLK_VAL field overlaps THT_EN bit acpi_tz0: <thermal zone> on acpi0 acpi_lid0: <Control Method Lid Switch> on acpi0 acpi_button0: <Power Button> on acpi0 acpi_pcib0: <Host-PCI bridge> on acpi0 acpi_pcib0: matched entry for 0.12.INTA (source \\_SB_.LNKB) acpi_pcib0: possible interrupts: 9 acpi_pcib0: routed interrupt 9 via \\_SB_.LNKB acpi_ec0: <embedded controller> on acpi0 acpi_cmbat0: <Control method Battery> on acpi0 acpi_acad0: <AC adapter> on acpi0 acpi_timer0: <24-bit timer at 3.579545MHz> port 0x8008-0x800b on acpi0 -- Yoichi Nakayama <[EMAIL PROTECTED]> E-ken, Dept. of Physics, Nagoya University http://www.eken.phys.nagoya-u.ac.jp/~yoichi/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
