Thread: Immediate wakeup from Suspend/Hibernate after 1st use of WOL ASRock E3C226D2I

    Default Immediate wakeup from Suspend/Hibernate after 1st use of WOL ASRock E3C226D2I

    I have an ASRock E3C226D2I mainboard and set it up to wake it using Wake on LAN (WOL).

    Steps to reproduce:
    1) Enable Wake on LAN via magic packet:
    ethtool -s eth0 wol g
    2) Suspend computer (S3) or Hibernate.
    3) Wake up the computer via magic packet.
    4) Suspend computer (S3) or Hibernate.

    Expected results:
    Computer should be suspended / hibernated.

    Actual results:
    Computer immediately wakes up again. After it has resumed, you can successfully suspend/hibernate it, without it waking up.

    Disabling WOL after waking up with ethtool does not change anything.

    There is a bugreport on
    Some other people with other motherboards are also affected.

    My system:
    Debian Jessie
    Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.7-2 (2014-11-06) x86_64 GNU/Linux
    BIOS P2.02s
    LAN where network-cable is attached: Onboard (Intel driver igb)

    sudo ethtool -i  eth1
    driver: igb
    version: 5.0.5-k
    firmware-version: 3.16, 0x800004d6
    bus-info: 0000:03:00.0
    supports-statistics: yes
    supports-test: yes
    supports-eeprom-access: yes
    supports-register-dump: yes
    supports-priv-flags: no
    It "seems" like the WOL package is still somewhere in the network card and does wake-up the computer a second time / isn't cleared after the first suspend/hibernate.

    Please tell me if you need more information about the system or other debug logs.

    My main problem is that I have attached several mechanical hard-drives and the need to suspend->wakeup->again suspend causes the drives to spin-down/spin-up one more time than needed, it is unnecessary mechanical "stress".

    Thank you very much for help!
