Bert's hot tip for the day:
If you're searching for a solution to a specific error message, use the message as a search string in google/linux. As other people have found the error, the probability is that they've posted the message to the developers - and you can search against their queries.
I'm not being facetious - it took me a while to work this out - error messages are very specific and the more specific you can make the search the better.
It could be that no-one here has seen this message. But someone will have.
