It would be difficult at best for anyone to answer your question very well with so little information. However, I googled your error message and the best info I found is at:
http://www.houseoflinux.com/debates/...missible-range
which shows it to be a warning, not really an error. I assume your machine actually does boot up and you are just seeing what looks like an error but is really just warning you that if there really were a crash during boot up that the system would not be able to kdump anything for someone to diagnose.
