--- Comment #9 from Abraham122x <abraham@gmx.at> ---
A very unprofessional approach I did yesterday, but just as curiosity.

The original Intel driver I compiled yesterday are not showing the WOL flags
anymore for my NICS.  Therefore I commented following "if" source code line=
 in
"if_igb.c":

/* APME bit in EEPROM is mapped to WUC.APME */
eeprom_data =3D E1000_READ_REG(&adapter->hw, E1000_WUC) & E1000_WUC_APME;
/* if (eeprom_data) */
  adapter->wol =3D E1000_WUFC_MAG;

After that, when I shut down the machine, the LED's of the NICS where still
active (as it should be with WOL). When I sent a WOL magic packet to the NI=
C,
the corresponding LED of the NIC was flashing. So the packet was arrived and
accepted, but unfortunately the machine was not powered on.

Does this someone help for further analysis?
