Strange Ethernet/PCIe Behavior with Clover & Chameleon

[SwithDrawn]

On 10.11.1, most of the time, I don't have working internet or USB3 (both the NIC and usb3 are PCIe cards). Occasionally, about every 4th or 5th boot, they will work. 

 

Even when it's not working, the NIC is detected under System Profiler and shows up as "Connected" under the Preferences, but I can't ping any addresses, even my router. I have tried flushing the cache. Same goes for the USB3 - hardware shows up but is not functional. 

 

I've had this problem going from Mavericks to Yosemite but fixed it by installing old versions of the following kexts: 

 

AppleACPIPlatform.kext (version 2.0)

IOACPIFamily.kext (version 1.4)

IOPCIFamily.kext (version 2.8)

IOUSBFamily.kext (version 675.4.0)

 

I have not been able to upgrade past 10.10.3 with these kexts due to dependencies changing, etc. I was hoping a clean 10.11.1 would just fix everything (naive, I know). The situation is the same with both Clover and Chameleon installations, and I've tried several smbios's (3,1 and 5,1, iMac14,2).

 

I have one other PCIe card - my 980 GTX, which works 100 percent of the time. My mobo (see signature) is a server board so I'm sure this problem is due to some strangeness related to how PCIe is set up on my board. I just don't know where to look or what to do to fix the problem. I thought about adding the cards to my DSDT but since they are always detected I'm not sure that would make a difference? I can also use IORegistryExplorer but don't really know what I'm looking for. Any guidance or suggestions are appreciated!
