OP said "will [they] even work?". That's a very different thing from a TLB bug. Although I concede that depending on the nature of the TLB bug, it may lead to a significant performance hit.
Regarding your criticisms of AMD's past processors, are you coming at this from a consumer standpoint, or are you just disappointed with their architecture and/or implementation?
I ask because the Phenom II seems quite loved by its users[1], and the FX series was also quite good for its price. I had a FX-8320 in my last PC and it was quite a capable CPU in my opinion, and many others seem to agree[2].
