@Suiseiseki @dushman >If I was intel, I would intentionally make the hardware microcode unstable and then release a encrypted, ultra-obfuscated, undocumented instruction set proprietary microcode update with a fix for the stability "issue" and all of the backdoors.

I agree, this is probably what's happening. Intel has so many security vulnerabilities, so often. they are probably planned and microcode is used to make an official "fix" while the NSA can use both the backdoors in the microcode and the "vulnerability" backdoors
