After looking at the interface closer it appears the device it is
plugged into does not have power.  In this case it is a Wimax wireless
radio.

Should a device with NOCARRIER cause this error non-stop in the logs?
  Can I get you more information that might help understand why the
watchdog is being tripped?

Thanks for your help!
