Comment 4 for bug 1745349

I have similar issues on my DELL R630 server but only on those with extra NIC:s.

In my case it is not triggerd on boot but when I start the openstack neutron agents components that starts configuring the extra nic (Intel 10-Gigabit X540-AT2 rev 01).

It works for me with 109, but I get the kernel lockup with 110.
