Hi,

I'm about to finish my new Skylake build and recognized something very strange:
My PCIe Gigabit Network card (Sonnet GE1000LA-E) with native support on OS X is not working.

That's what I was able to find out:
* an attached network cable will be detected
* the OS starts sending DHCP requests, etc. (validated using tcpdump locally)
* the OS will never receive any packages (validated using tcpdump locally)
* the card never actually sends packages (validated using tcpdump on the other side)

Syslog:

Any ideas what's going on here?

All of the PCIe slots on the motherboard are conform to PCIe 3.0 standard.

The Sonnet GE1000LA-E is not compatible with PCIe 3.0 slots.
