I am sorry for jumping in on this so late.

Since using a Lenovo X60t more ofter since a year or so, I experience 
the issue, that the link doesn’t come up during that period occasionally 
[1]. I haven’t tried the latest patches yet, but it might be unrelated.

Did you test, that removing and loading the e1000e module fixes the issue?

Additionally, I was asked privately to test the out of tree driver, but 
haven’t had time yet.

Kind regards,

Paul
