Hi all,

I've got a rev 2 G31M-ES2L and a Netgear GA311 PCI card (RTL-8169 based).

I was having problems with internet connectivity, saying the cable was unplugged - messages "AppleRTL8169Ethernet: IOInterruptEventSource error"

I tried the Psystar driver, the driver from the Realtek website, a downloaded AppleRTL8169Ethernet.kext but still no joy.

In the end I deleted AppleHPET.kext and AppleIntelCPUPowerManagement.kext from /System/Library/Extensions and everything now works.

Hope this helps somebody.
