Can anyone point me to the right direction?
I'd like to go with FreeBSD 8.1 amd64 for my next system.
Hibernation and Wake on Lan would both be useful.
The only support for hibernation is via the BIOS with a special
partition. Unfortunately as far as I know it rarely, if ever, works.
Windows (I don't know about Linux) bypasses the BIOS/ACPI and just
dumps the contents of memory to disk before powering off.
My current system (6.4, really old hardware) shows this:
sysctl -a | grep -i hw.acpi
hw.acpi.supported_sleep_state: S1 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S1
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.reset_video: 0
hw.acpi.cpu.cx_lowest: C1
ampd is the command I'm looking for ?
Also what is the differences between Sleep, Stand By, Hibernation and
Suspend?
