Not the first bug reported for Ryzen. Wasn't there a couple of others too, one with linux locking up and another triggered by the ocaml compiler emitting opcodes refering AH/BH/CH/DH registers in a tight loop?
Edit: Sorry, the ocaml bug was Intel Skylake. It's interesting how so many new CPUs have breaking bugs. Feels like it's been quiet since the original pentium F00F bug and then all of a sudden everyone's new CPUs break.
it mentions something that I really worried about - Intel knowingly requested its own validation efforts to be reduced so they can place half baked products onto the market faster. pretty sad that both Intel/AMD are seem to be cutting corners to just be a little bit faster in the competition.
