This is a minor problem, as you will see when you read the article. AMD probably ought to be commended for expending the effort they are to alleviate any problems.
Intel once had a similar problem with early Pentium processors and it caused them no end of bad publicity. Admittedly, their problem was bigger than AMD's current one it. The risk of bad press is probably why AMD is being so aggressive in tracking down the affected parts and replacing them. Or maybe they are just being honorable. It wouldn't be the first for either.
