Post Intel 82579 GbE PHY hung on linux
I've been battling this problem with the intel ETH since I've ordered and installed my Intense PC. It is being used as a gateway and webserver for my network, but the intel 82579 GbE PHY hangs and needs to be reset. I'm running a version of Arch Linux (Artix Linux) and I have taken this to the intel forums with limited results.

Code:
[343103.324582] e1000e 0000:00:19.0 eth1: Detected Hardware Unit Hang:

Please test the system in a known to work environment we fully support such as Windows or Linux mint.
Linux mint 19.1 installation instructions:

Also, you may find additional information on how to install Windows in either Legacy or UEFI mode at:

* The drivers are included for all supported windows version at the link above.

No, we don't put linix mint on anything and certainly not windows.

This is a kernel level problem with a standard driver. It is a little insulting, after buying what is now my 5th Compulab device, you have a returned response like this, which assumes I am an idiot and demands something ludicrous. This box in in production. All linux kernels and drivers are the same, even for a stupid distribution like Mint. Please just let me have an e1000e driver that works with the hardware.

BTW - when I purchased this it came with SuSE preinstalled.

Hi mrbrklyn,

I see something similar here:

Possible solution is:

Ok so after posting this question last night night I continued to do some research the only real solution I came across seems to have taken care of the problem.
Disabling TSO, GSO and GRO using ethtool:

ethtool -K eth0 gso off gro off tso off

According to a post found here: http://ehc.ac/p/e1000/bugs/378/
From what I understand this will or can cause a reduction in performance.
