> Hi, we still encounter this error in the latest 4.4.0 kernel.
yes, unfortunately, the last patch seems to have helped reduce the
frequency, but i did recently get another report of it happening again.
So it seems to not be completely fixed.
To clarify, as I said before, this is an event

Due to the nature of this bug, being very difficult to reproduce, real
verification could take weeks instead of only days. However, one reporter has
been running with a test kernel I built here

Hi there. I can confirm this problem still exists in newest kernels and
with the latest intel drivers as of today:
Jan 19 16:05:19 osd9 kernel: [511271.581413] i40e :02:00.1: TX driver issue
detected, PF reset issued

Sorry for the delay, I've not forgotten about this, just been swamped
with other things. Will hopefully have time to do the tests next week.

ok, so first, these instructions may cause the card to hang; the system
may need to be rebooted or the driver reloaded. The changes here can be
undone by resetting the card;
No worries, we're not in a hurry.
I'd say we go with option #2. Please provide information on how to
proceed, and how to undo any changes we test :)

Sorry for the delay.
So we have 2 options on how to continue debugging here:
1. we can try a traditional git bisect. This would involve testing
various kernel builds, to try to eventually narrow down the issue to
being fixed by a specific commit. It's a long-ish process, depending on
how long
kernel v4.10, (4.10.0-041000-generic) has been running fine, without any
issues since 24 hours. I'd say it's OK, as you suspected.

Absolutely! I just mentioned the "GRO implementation" because I wondered
if it might have been related. I should have googled up better on it
beforehand, that would have enlightened me that it wasn't.
I've tested the v4.4-wily kernel in the first link
> How do we proceed? :-)
one bug at a time, please. As this NIC's "MDD" behavior doesn't
indicate what happened that it disliked, I can't tell if that is related
or not to the MDD events, but I suspect not, especially if you have not
seen that happen for kernels when you did get MDD events.
As of now, we've been running HWE 4.10 for little more than 16 hours and
no problems so far. Previously we'd hit the problem within the hour.
There is however one new logmessage that we haven't seen before, neither
with 1.4.x driver or 2.0.x. But it might be unrelated, we can't see any

yes please it will help to look just between 4.4 and 4.10. thanks!

continuing conversation from previous (fix released) bug.
@bjozet, it would help a lot of you could test with the hwe 4.10 kernel
and let me know if that fails also, or if it seems to be fixed there.
If it works, I can review the changes and possibly find something,
and/or work with you on a
