Intel Skylake/Kaby Lake processors: broken hyper-threading

On the other hand, if you state very publicly and with great confidence that you are sure there is a bug in someone else's software/hardware/etc because you've checked extremely carefully and there's no possible way the problem could have been caused by your own code, and especially if you imply they are idiots for making such mistakes, then within a couple of hours (just slightly too late to retract your accusations) you are highly likely to discover the blindingly obvious bug in your own code. The universe seems to have a tendency to maximise embarrassment like that.

If you're willing to put up with the embarrassment, it's a very quick way to get your problems solved.
