FYI still happening to me on 18.04 with HWE kernel,
similar behavior as #38: kworker with steady high
cpu usage after un-docking, re-docking didn't solve
it tho.

FYI this is also happening for me, LTS 16.04.3 + HWE (kernel and xorg pkgs),

We really need to get xenial added for its HWE kernels:
we have several BootStacks running with them, mainly for
latest needed drivers while keeping LTS (mellanox for
VNFs as an example)- all these are now obviously at
risk on the next reboot.
Note also that recovering from this issue does

Because linux-image-generic pkg doesn't include mlx5_core,
stock ubuntu cloud-images can't be used by VM guests using
mellanox VFs, forcing the creation of an ad-hoc cloud image

equivalent setup w/ LXCs frames hitting phy interfaces

FYI we found these issues while deploying openstack via juju/maas
over a pool of 8 nodes having 4x i40e NICs, where we also found
linux-hwe-generic-trusty (lts-utopic) to be unreliable from its old
i40e driver (0.4.10-k).
Below is a summary of our i40e findings using lts-vivid and lts-utopic
re:
ERRATA on comment #2 : OK i40e driver version is 1.2.48,
as per original report URL.
Comment #2 table is actually:
#1 3.19.0-28-generic w/stock 1.2.2-k: non-phy mirrored frames (this bug)

Public bug reported:
Using 3.19.0-28-generic #30~14.04.1-Ubuntu with stock i40e
driver version 2.2.2-k makes every 'non physical' MAC output
frame appear as copied back at input, as if the switch was
doing frame 'mirroring' (and/or hair-pinning).
FYI same setup, with i40e upgraded to 1.2.48 from
