Description of problem:

Noted the following warning in journal:

I have only noticed this, but it may have been present since a recent upgrade to F19.

Version-Release number of selected component (if applicable):

 3.11.2-201.fc19.x86_64


How reproducible:

Present on every re-boot.

Additional info:

Is this something to be concerned about?
