[SOLVED] Intel NIC e1000e hardware unit hang

[sloppyjoe]

that seems to have fixed it for me.
I have no performance problems and no more problems are visible in the log since then:

ethtool -K eth0 gso off gro off tso off tx off rx off rxvlan off txvlan off

Really appreciate the help with this as the constant disconnects were driving me crazy!

This fixed my issues with the Intel i219 adapter in my Lenovo M920q.

It seems that this fix needs to be applied every time you restart. So remember to set it up in systemctl or however you run your startup scripts.

lspci | grep -i ethernet
