Intel Skylake/Kaby Lake processors: broken hyper-threading

It's not overblown if your computer is the one that keeps crashing.

Does it need immediate patching? That would depend I guess on whether you've experienced a bunch of unexplained crashes or corrupted data. From some of what I read it's a pretty difficult bug to trigger but if you're the guy with the code that's triggering it you probably want a solution. One thing I can say, it's pretty friggen cool that Linux saw the patch so fast, it'll be a month before windows gets it.
