That mapping value looks like you had a single bit flip in your guest.  Have you gotten this more than one time?
Comment 3 Jan Sedlák 2013-09-26 10:12:46 UTC 
No, I haven't encountered it since.
Comment 4 Josh Boyer 2013-09-26 12:15:17 UTC 
OK.  Let's close this out for now.  If you see it again, please reopen.
