I have run the first test on several machines, with mixed results, but on my workhorses (ThinkPad x220, Zenbook UX305) the exploit seems to work.

I thought the recent kernel-/firmware-/ucode-patches should have prevented that.

EDIT: The other demos fail, though, as they should. sigh

EDIT: For some reason, demo #2 (breaking kaslr) works on my Ryzen machine, but not on the others. :-?

Spectre should work on most modern computers. There are no kernel patches in stable to prevent Spectre right now. Only Meltdown is mitigated by KPTI. The new Intel microcode and the kernel code to control it will propagate out in the next couple of weeks.
