Ok, i re-checked every possible setting that i found.

1.) Hardware / Mainboard should support wake on lan according to the manual
(http://asrock.pc.cdn.bitgravity.com/Manual/C236%20WSI.pdf), Page 4 (10 in
PDF):

This motherboard supports Wake from on Board LAN. To use this function, please
make
sure that the “Wake on Magic Packet from power off state” is enabled in Device
Manager
> Intel® Ethernet Connection > Power Management. And the “PCI Devices Power On” is
enabled in UEFI SETUP UTILITY > Advanced > ACPI Configuration. After that,
onboard
LAN1&2 can wake up S5 under OS.

The "Device Manager" Part is for Windows i think, but i attached BIOS
Screenshots for the EFI ACPI Configuration.

2.) PCI Devices Power On is enabled as described above

3.) Both LAN-Ports are Enabled (See lan_enabled.jpg)

4.) Sysctl and ifconfig

I configured:

dev.igb.0.wake=1
dev.em.0.wake=1

AND

ifconfig igb0 wol
ifconfig em0  wol

with and without reboots to ensure state is available... none worked. 



If theres something else i should check, feel free to point it out. Last things
to check would be:

1.) The patch Kaho Toshikazu send me (thank you very much)
2.) Check for a newer BIOS / EFI Update 

But this could take some days.
