This protects system from hanging if RIO link fails or enters error state. In some situations following maintenance read may initiate link recovery from error state. As it is now, MCheck mostly prevents system from hanging, but it also adds sense to return status of maintenance read routine. I am using return status in my new set of patches to check if RIO link is valid during error recovery.
