Title:
Intel Ethernet I218-V [8086:15a1] Subsystem [1043:85c4] detected
Hardware Unit
I gave up on this ever being fixed since it's existed since 2.6 and
went and bought some Realtek ethernet cards, no problems since. But, you
can work around this bug by turning hardware offloading off if efficiency
isn't an issue.
I am also experiencing this issue.

I also have this problem on an Intel DQ45CB mainboard with the onboard
Intel 82567LM-3 Gigabit ethernet controller. The syslog fills up with
following entries, while network connection is being reset. It does not
happen immediately after boot, but high throughput seems to trigger it.

FYI, in reference to some of the comments here about this being
intermittent, the way I can trigger this reliably is via streaming via
Twitch -- which is not even something I do with any regularity. I will
see the stream die as if buffering, and inevitably that will correspond
with this error in

We're seeing this bug consistently (although not consistent per se - the
error does not occur immediately after boot, and doesn't immediately
disconnect the server from the network; anything from 3 weeks to 3 hours
before it starts, and a day or so after is starts before it gets

4.14.0 final crashed hard after running 17 hours. Not only was the
ethernet not-responsive, neither was the console, not even the magic
sys-req key. I had to power cycle the machine to get it unhung. Then
I booted 4.14.0rc1 and it immediately exploded however I had set a 20 second
time out and

4.14 has the problem. Do I need to try the 4.15rc0 kernel also since
4.14 isn't well?

We could perform a kernel bisect to identify the commit that introduced
this regression. To perform a bisect, we need to identify the last
kernel that did not have the bug and the first kernel version that did.
Do you recall the last kernel that didn't exhibit the bug? If not,

Just to make sure you got the latest, the 4.17.x kernel did not work well

Strangely it broke nfs-kernel-server on the i7-6850k machine but not the

There is a 4.50.0-20.21 in Proposed, is this the correct kernel?
