I don't know whether it relates to the same problem, but I couldn't properly upgrade a system running 6.0 + CR that wasn't at the latest patch level when 6.1 came out. Lots of messages like the one you showed. The solution was to temporarily disable the centos-release-cr repo, then upgrade, then re-enable CR again: yum remove centos-release-cr yum update yum install centos-release-cr I assume the reason is that the CR repo for 6.0 has been pulled with release of 6.1 whith the catalog still in place.
