Another possibility for troubleshooting is to boot with 'biosdevname=0' to avoid the stable name that munges things up on occasion. Also see "Consistent Network Device Naming in Linux" (http://linux.dell.com/files/whitepapers/consistent_network_device_naming_in_linux.pdf). I've found biosdevname=0 is hit or miss. It worked for a while, but then later 4.x kernels stopped honoring it. Jeff
