Intermittent connectivity loss with em(4)

[Morgan Wesström]

> I have had issues with em nics in the past and don't use them anymore.  However, none of the issues were as blatant as you are seeing.  The dmsg log is only written to during boot.  Messages during operation are written to /var/log/messages.  Check there to see if there is anything that correlates with the outages.

Yes, I did check /var/log/messages too but there's nothing written there 
during the outages unfortunately.
