It looks like it was due to the pci addressing. The npci command in the boot.plist this is from tonymac: Because the npci=0x2000 and npci=0x3000 has to do with initialization of the PCI configuration space and when to initialize the signal. It has changed with this update and future updates from what I'm gathering.
Hi All, I've rea this entire thread. I just updated my install from 10.8.3 to 10.8.5 and the network interface is not reported in the system report I am between 10.8.1 and 10.8.3 I was using AppleIntelE1000e.kext version 1.9.4 I am now trying 2.4.14 with no success. My motherboard is an Intel DP55wb. Any help would be greatly appreciated. It's fixed. I removed npci=0x0300 from the boot.plist file. What a pain.
