Debian Project Warns: Turn off Hyperthreading with Skylake and Kaby Lake

https://lists.debian.org/debian-devel/2017/06/msg00308.html

Try having some tact and check into things before you accuse HH of posting fud :bang:.

 

I wouldn't say so. Debian is probably more pro-Intel than they are anti-Intel. It wouldn't surprise me if they have a larger Intel user base (vs AMD) compared to, for example, Ubuntu. They're not saying to avoid buying these products, but to stop using HT at least until a microcode update is released.

Debian's devs are pretty attentive when it comes to security and stability, so when they observe an issue, you ought to take it seriously. On the other hand, Debian has a tendency to use pretty outdated software. Makes me wonder if there's a possibility that these CPUs (or at least the microcode) may conflict with older software in some way. I'm not saying that means Intel isn't responsible for this problem, but rather maybe some people are less prone to facing this problem than others.

 

Everyone blaming microcode or bioses, but real culprit is that new procesors are not compatible backward, it means they will not run older code, all because colaboration with microsoft and strong push to windows 10

 

In the face of something you don't understand and are too lazy to look into, just saying "Fake news" is so much easier and satisfying.

 

ATOMIC pipe errors are intel specific.

 

isnt that even on bios there is something called "No-Execute Memory Protect" things ?
not sure how much different with UEFI secure boots, never been care much about it and always though its similar things

 

Yes, amazing the number of responders here that didn't read the article and gather info like the official errata number from Intel, or catch that it has to come through a bios-only microcode fix, since obviously the fix has to be applied in every boot before the OS boots. Do people only read the first two lines and then quit?... Always a good question these days.

 

I have that enabled. It stops certain code from running or marks it as non excuitable.

 

This sounds just like that original issue with Skylake that was fixed in Kaby Lake.

 

this dont effect my cpu(R0), by time I got my 6700k the cpu was year old,
But this does sound like original issue with skylake, which again isnt issue on mine.

 

I think it has to do with Intel being really salty about the EU case. Latest article I've seen on it http://www.businessinsider.com/r-eu-court-seen-ruling-on-intel-antitrust-case-next-year-judge-2017-6

 

If you want to update your microcode on windows to the latest you could follow this link (NBR forum post)

Did it on the laptop and the code update applied after reboot.

 

Well,

I use this tool to update my CPU Microcode Automatically to latest which is Version BA !
Enjoy

These microcodes are safe?From official source?

Could be Fake news.If you disable HT what performance you have after? 30-50% off?

Edit: I found the white-paper from Intel,for 7th Generation Intel Processor Family

https://www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-spec-update.html

 

Intel have microcode download links on their website for linux. For Windows they are part of Windows update. The last release was in 2016 as far as I can tell.

 

You, sir, do not deserve an answer. Not bothering to even READ, yet bothering to say "could be fake", thus accusing HH (and Debian) of spreading fud, is just detestable and obnoxious.

 

Yes, it's fake news. Debian is a known fake news outlet. Not to be trusted. Intel released new microcode to fix the fake issue. Microsoft is including the microcode in Windows Update to fix a fake issue.

Fake news. Totally.

 

"fake" "news"?

Have we stooped so low, really?
