I've pushed some test kernels for X/B to a public PPA assigned to this
bug [0], hopefully it'll make validating the upstream patch a bit
easier.

The patch [0] is present in Ubuntu releases starting with Focal, so it
should be fixed for that and later releases (including current bionic-
hwe). I'll look into backporting and testing this for Xenial and Bionic
GA.

@fayomidimeji, my comment 4 applies to you as well.
Additionally, you both might want to verify you are actually seeing this
problem, and not something else.

Hi,
We have disabled TSO and GSO and we are still experiencing the interface
resets. This usually happens under high load.
Kernel version: 4.4.0-135-generic
driver: i40e
version: 2.4.10
firmware-version: 6.01 0x80003493 0.0.0
bus-info: :05:00.1
supports-statistics: yes
supports-test: yes
@terryh-orcas,
if you are able to reproduce the problem relatively quickly and easily, then I
suggest testing different kernel versions, up to the latest upstream, to see if
and where it may be fixed with a newer i40e kernel driver. You can get
upstream kernel debs here:
We are getting this error on all of our new systems (Dell 14G C6420)
running Xenial. I've tried 4.4.0-139-generic. I'm now trying
4.13.0-45-generic and see if it still shows up there.

as I can't reproduce this, and I have heard no more reports of it, i'm
marking this as incomplete. If anyone does actually still see this
problem with the latest (x/b/c) kernel, please add a comment to this
bug.

For details about i40e registers that may be able to help debug the
cause of this, see bug 1723127 comment 10.
Also, a (possible) workaround to avoid this error is to disable TSO on
the i40e nic.
