GA-Z77X-D3H auto restarting after shutdown (WOL issue?)

[Vectorspace]

My GA-Z77X-D3H (rev 1.1) machine is auto restarting after shutdown. I do not mean it reboots instead of shutting down. I mean it actually powers off - fans off, power light off - and after a few seconds spontaneously powers on again.

I have noticed that this only happens when I start the machine using Wake On Lan, so I assume it's an issue with that.

Peculiarly, the Wake on Lan option is missing from the BIOS? BIOS version is F16, which according to the support page is the latest non-Beta version.

The machine is a fileserver running FreeNAS, which is based on FreeBSD.

Does anyone have any suggestions

Hi,
WoL is possible, but what is often more likely is a power configuration incompatibility.  Might be related to keeping the NIC powered waiting for wake packets

A component or connected peripheral.

In the end, however, this is usually a power related component, hybrid hibernation file, etc.

I've not played with FreeNAS.  What kind of logging does it have?

I don't know, all I know is it's based on FreeBSD.

In terms of peripherals, it doesn't have any. All it is case, PSU, motherboard, processor, RAM, and 5 HDDs. Not even a discrete graphics card. Nothing plugged in to it except for power cable and ethernet cable.

Hi,
Just curious, do you have ErP enabled?  If so, this disables WoL and if I recall, hides it from the BIOS menu
