Bug Description
[Impact]
Sean Feole discovered that if you ifdown/ifup the NIC on an X-Gene 2 system, the NIC does not come back online. While the interface is reported as up, you cannot ping the system. In addition to the obvious problems this causes for a sysadmin, it also breaks software that does this automatically, such as juju when it sets up a host bridge.
[Test Case]
Boot an X-Gene 2 system, and start pinging it from a remote system. Assuming the pinged interface is eth0, run:
$ sudo ifdown eth0; sudo ifup eth0
System will cease responding to pings.
[Regression Risk]
(Still under investigation)
