Problem on AMD64

[David van Kuijk]

Hi

I try to put my machine in sleep state but get the message that this is
not supported.

command and result:
$ acpiconf -s 4
acpiconf: request sleep type (4) failed: Operation not supported

I get the same message for other sleep states 1,2,3.

My machine is a HP Proliant ML115 AMD64 running FreeBSD 7.0-RELEASE

Result from sysctl hw.acpi is
hw.acpi.supported_sleep_state: S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S4
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
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: 0
hw.acpi.cpu.cx_lowest: C1

$ dmesg | grep acpi

Anyone suggestions to a solution or is this a bug?

Best regards,
