I remember when Sr Managers at Intel were forced to outsource CPU validation to Costa Rica.
These things never happened back 10 years ago.
Other than the FPU flaw which was covered up by an Executive from India.

So Intel put out an alert!

And Debian gave more detail.

Tech post with the obligatory anti-Trump snark...

Symptoms can include application and system misbehaviour, data corruption, data loss and voting Donald Trump. We made the last one up.

They just blew their credibility out the water............

This does not bode well for Intel.
One of the reasons people are willing to pay more Intel chips
are dependability and flawless performance.

Another door for AMD has just opened.

" However, until they do that, it would be [wise] to disable hyper-threading or even shift to AMD."

Oh, is that all? As if you could just run down to your local Best Buy, grab an AMD chip, and swap the processors. Sure - I'll get right on that.

Related useless trivia:

For desktop cpus, Intel Core i3 and Core i7 cpus utilize hyperthreading.

Intel Core i5 cpus do not have hyperthreading, although Core i5 cpus are generally faster and more powerful than i3 cpus because they have more real cores (hyperthreading adds virtual cores).

For example, my desktop computer has an Intel Skylake i5-6500 which has 4 cores but no hyperthreading. Despite this, benchmark testing shows that the i5 is faster and more powerful than the i3 skylakes because the i3 come with just two real cores.

This is really only a necessary precaution if you are running these CPU’s on critical up-time infrastructure like web or database servers.

A Bios update fixes the problem.
Just did mine.
