Hi Roland,
Can you give the output of ethtool -i ethx and ethtool ethx?

The register dump did not give me any clues to the failure unfortunately.

3.120h vs 3.7 kernel has quite a few differences unrelated to phy. The two phy 
related differences that stood out are
  - In 3.120h EEE is off by default and turned on by a module param. The 
upstream code it's always on.
  - Link flap avoidance code was absent in 3.7. I has since been merged into 
net-next.

You mentioned newer kernels. How about older kernels?
 From your email, it seems like the issue happens immediately. Is it possible to 
bisect this failure if you find a working older version upstream?

Another thing to try would be latest net-next with eee disabled as below.

Nithin.
