Pete, something you just don't get is that Intel publishes their errata without NDA, it's open for the world to see, and yet OEMs still seem comfortable shipping Intel products. That says something about the way in which these bugs manifest, that they aren't going to be exposed under real world conditions.
Now, on the other hand, AMD has an errata that has all OEMs stopping shipments, and AMD calling for an official STOP SHIP of all Barcelona products of all frequencies. Now, I guess you are oblivious to the difference here, but let me explain the obvious:
OEMs are concerned about AMD's errata, which they try to hide from consumers under NDA, but not concerned about Intel's errata, which are public information for all to see.
Now, if you are still confused, Pete, then you're going to have to get used to living in ignorance.
