Thanks. I just lost the access to the machine today. So I have to use
another host in a different data center. Will resume testing in a few days.

> Title:
> [i40e] LACP bonding start up race conditions
>
> Status in linux package in Ubuntu:
> Triaged
> Status in linux source package in Xenial:
> Triaged
>
> Bug description:
> When provisioning Ubuntu servers with MAAS at once, some bonding pairs
> will have unexpected LACP status such as "Expired". It randomly
> happens at each provisioning with the default xenial kernel(4.4), but
> not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
> (Dell-branded).
>
> Using the HWE kernel works as a workaround for short term, but it's
> not ideal since 4.13 is not covered by Canonical Livepatch service.
>
> How to reproduce:
> 1. configure LACP bonding with MAAS
> 2. provision machines
> 3. check the bonding status in /proc/net/bonding/bond*
>
> frequency of occurrence:
> About 5 bond pairs in 22 pairs at each provisioning.
