Title:
[regression] Intel 10Gb NIC Crashes
Status in linux package in Ubuntu:
Confirmed
Bug description:
I posted this to netdev@xxxxxxxxxxxxxxx as well:
http://www.spinics.net/lists/netdev/msg309110.html
I think the next step is to try to bisect this down to a specific commit. I'm starting to look at the instructions here:

I'm seeing the same sort of crash/warning (skb_war_bad_offload). It's
happening on Intel 10 Gig NICs using the ixgbe driver. I'm using bridges
(for virtual machines) on top of VLANs on top of 802.3ad bonding. I'm
using an MTU of 9000 on the bond0 interface, but 1500 everywhere else.
I'm always bonding two ports: one one system, I'm bonding two ports on
identical one-port NICs; on another system, I'm bonding two ports on a
single two-port NIC. Both systems exhibit the same behavior.
Everything has worked fine for a couple years on Ubuntu 12.04 Precise
(Linux 3.2.0). It immediately broke when I upgraded to Ubuntu 14.04
Trusty (Linux 3.13.0). I can also reproduce this using the packaged
version of Linux 3.16.0 on Trusty.
In contrast to other reports of this bug, disabling scatter gather on
the physical interfaces (e.g. eth0) does *not* stop the crashes
(assuming I disabled it correctly).
I currently have two systems (one with Precise, one with Trusty)
available to do any testing that you'd find helpful.
Here's a first pass at getting some debugging data.
The broken system (Ubuntu 14.04 Trusty):
