OpenBSD disables Intel’s hyper-threading over CPU data leak fears

Re: Let's start a list...

Mostly true, maybe, but I am willing to bet that any mitigation will be multi-part: microcode, kernel and applications. Just like the rest of the Spectre work that has gone on. People will want to know if they have to patch an application that they depend on. Also, the way that code is optimized for SMT may have to change.

I could be wrong, but I don't think OpenBSD would make the change unless they have a damn good reason to. They are a very conservative distro known for tight security. If they are going so far as turning off SMT altogether then my money is on something big and complicated.
