[TriLUG] CentOS 6 with kernel v3 - bonding interface drops

[John Broome via TriLUG]

As a troubleshooting measure, could you boot a Fedora live CD and see if
you have the same issues with that kernel (3.17.4.x from the mirror i'm
looking at).  Centos7 is 3.10.x, which is older than what you've tried.
