  > Under a complex set of internal timing conditions and system events, software using the Intel TSX (Transactional Synchronization Extensions) instructions may result in unpredictable system behavior. Yeah, that's nice and descriptive. Damn. :/

  I read through this and found the TSX errata as #136 on a list of 140 issues. I was pretty surprised; some of these issues are major, showstopper crash bugs (admittedly mostly only affecting operating systems developers, and many with workarounds.) Just reading through these issues, I see a handful that deal with specifically with external (proprietary?) hardware integrations, like with integrated Intel graphics boards. Why is the CPU loaded up extra jazz for with specific integrations like this? Is this to support a system-on-a-chip optional kind of configuration, or is this Intel trying to give themselves some sort of advantage in the graphics adapter market? If it is the latter, then it serves them right to have these errata and instability due to adding all that extra competitive advantage nonsense on the chip.
