I've downloaded kernel 4.6.0 from kernel.org, patched using

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1583750/+attachment/4666376/+files/0001-e1000e-added-more-error-output-during-probe.patch

To increase verbosity of e1000e, and after a cold boot, I got this:

~$ dmesg | grep e1000e

On warm reboot, log shows:
