If is is x86 instruction set one would think it can be stopped at OS level, or worse might apply to AMD as well.

As of yet, no documentation has been published to back this claim up and until it is this has to be taken with a large dose of salt. That said, x86 is Intel IP and if it turns out to be true it shouldn't really come as a shock. If "Meltdown" was zero in a 1 to 10 scale, this would be a 7 and could well have worldwide ramifications especially as it's now in the public domain.

Damn, I better unplug my PC right now, there goes movie night (and 2 hours of fapping later).

Not good if true - struggling to verify this is genuine, anyone else got some links with more detail / discussion beyond the twittersphere?

I'll be interested in following this. Not much I can do about it as I can't afford a new computer if it is true so I just hope there is a fix.

(Tinfoil) wonder if this is an instruction Intel added for certain three-letter agencies?
If this turns out to be true, it would be interesting to see how long and widespread it has been undocumented.
Supposedly user mode too:

So not sure if the OS could trap the instructions then.

With regards to how long, someone in the Twitter thread saying its present in the P6 arch - so at least since mid 90's if theyre correct - unless I'm reading this wrong

Hope this develops into some entertaining drama.
