DSDT Ethernet after wake

[Hutch]

Hi all,
I have a Zotac G-E LGA775 ITX motherboard. However, the ethernet doesn't work after wake from sleep. I gave it a go trying to fix it using both of the following in the _WAK method to no avail.

Notify(\_SB.PCI0.GIGE, Zero)
Store(0x01, \_SB.PCI0.GIGE)



IOReg

_WAK from DSDT

Method (_WAK, 1, NotSerialized)
    {
        Store (0xFF, DBG1)
        Store (Zero, SFLG)
        If (LEqual (RTCW, Zero))
        {
            Notify (\_SB.PWRB, 0x02)
        }
	Store (0x01, \_SB.PCI0.GIGE)
        Notify (\_SB.PCI0.OHC1, Zero)
        Notify (\_SB.PCI0.OHC2, Zero)
        If (LGreaterEqual (OSFL, One))
        {
            Store (Zero, \_SB.PCI0.SBUS.SMPM)
        }

        Return (Zero)
    }

Using Store (0x01, \_SB.PCI0.GIGE) produced a black screen on wake and I have to reboot.
