Thanks, that does sound identical to my symptoms.

However I tried applying this patch to my driver in 4.9 and it does not 
resolve the problem.

Are some additional patches required as well?


FWIW, I added some extra logging around the new code.  I can confirm 
that it does execute on link regain but doesn't actually enter the loop 
in my problem case.  The pcim_state is 0x00080083 at the time.  So the 
e1000_phy_hw_reset is never actually called.  If I try changing it to 
call that unconditionally, then it can't successfully establish a link 
in the first place.
