Off the top of my head, I cannot think of anything that has been added to the driver in
Linus' tree since 3.10 that would cause this change in behavior. There are a number of
changes that have been put into the out-of-tree driver which have not yet made it into
Linus' tree - would you be willing to try the latest out-of-tree driver from e1000.sf.net
to see if it resolves your issue? Of course, a bisect as you mention would also help.

Have you checked for a BIOS update from your system manufacturer?
Do you have Runtime Power Management enabled for this device?

Thanks,
Bruce.
