Description R. Tyler Croy 2014-02-13 18:20:00 UTC

Currently at -CURRENT with r261524. Not sure what the cause of this, I've not been able t reproduce it consistently. However, when it starts happening, it seems to happen constantly until a reboot or suspend event.

After this happens, I'll usually try a `service netif restart` which gives me connectivity back for some amount of time, but within 5 minutes the error happens again.
