How are we suprised at all of this ... it's @zMeul on his anti AMD propaganda war once more. "Oh look, a brand new arch has some teething problems, how AMD have screwed up again". Both AMD AND Intel have had, and will continue to have issues with new architectures when they are so radical.
Having had both Intel and AMD platforms, this is not something that worries me, nor should it anyone else (In my humble opinion). It's simple scaremongering to start telling people that there may be a full scale product recall on the horizon. Stop it and grow up.
