New HyperThreading Flaw Affects Intel 6th And 7th Generation Skylake and Kaby Lake-Based Processors (hothardware.com)
MojoKid writes: A new flaw has been discovered that impacts Intel 6th and 7th Generation Skylake and Kaby Lake-based processors that support HyperThreading. The issue affects all OS types and is detailed by Intel errata documentation and points out that under complex micro-architectural conditions, short loops of less than 64 instructions that use AH, BH, CH or DH registers, as well as their corresponding wider register (e.g. RAX, EAX or AX for AH), may cause unpredictable system behavior, including crashes and potential data loss. The OCaml toolchain community first began investigating processors with these malfunctions back in January and found reports stemming back to at least the first half of 2016.
The OCaml team was able pinpoint the issue to Skylake's HyperThreading implementation and notified Intel. While Intel reportedly did not respond directly, it has issued some microcode fixes since then. That's not the end of the story, however, as the microcode fixes need to be implemented into BIOS/UEFI updates as well and it is not clear at this time if all major vendors have included these changes in their latest revisions.

All you losers with your over-priced Intel crap.
I've used nothing but AMD for 20 years and I have absolutely no probl%#^$^%J NJasllodofufm DUDFUF&&()()FDJJDNDMS .......
Are you complaining about the topic as being too insignificant to deserve an article (as in: no need to tell people that they way want to update their servers) or are you preemptively commenting that other readers shouldn’t bother to comment on such an insignificant topic?
If you don't know the model name of your processor(s), the command below will tell you their model names. Run it in a command line shell (e.g. xterm): /proc/cpuinfo | sort -u
grep name
C:\>grep name /proc/cpuinfo | sort -u
'grep' is not recognized as an internal or external command, operable program or batch file.

Your terminal is throwing weird smilies at you. I think it is cross with you.
