A suggestion, take the relevant files from my em driver and put them back into the kernel tree that was working on 10/1, it should be compatible. Then see if it breaks that kernel. Or if you'd prefer I can just email the tar ball for the Intel version of 6.6.6, you can disable the in-kernel em driver, and build the other and use that with the 10/1 kernel.
Let me know what you'd prefer.
