Linux Kernel 6.1 Introduces Faulty CPU Core Detection Logging Feature (UPDATED)
This isn't a fully automated system, and it's only for logging; it won't stress the CPU to check for faults. As a result, Rik Van Riel — who is responsible for authorizing the CPU logging system for 6.1, says system admins will want to run commonly run kernel code known to cause faults with a known faulty system with the logger enabled to see which cores are bad.
The logger isn't perfect, since the kernel tasks might get rescheduled toward another CPU or CPU core, but he finds this strategy to be good enough to find bad CPUs or cores. Often times, CPU faults can be "oddly specific" where specific programs or pieces of code will crash the core only.
This program isn't really designed for consumers, but is aimed primarily at system admins running a host of Linux-based servers. For these admins, this new tool can be really useful for hunting down mysterious hardware faults when full blown CPU stress testers such as Prime95 or Aida64 are perfectly stable.

Linux 6.1 will tell you when your CPU is crocked | TechRadar
Linux users are set to get a new way to identify faulty CPUs, with Linux kernel version 6.1.
The new feature will allow users to print the socket and core which are likely responsible when a segmentation fault occurs, which should allow users to spot if a particular CPU/core is routinely causing problems.
This might not mean much to the armchair Linux enthusiasts, but sysadmins running a fleet of Linux servers stand to benefit.

Chipzilla goes all open saucy
Apparently, there is upstream, open-source support for Intel Arc Graphics on Linux albeit not enabled by default as of Linux 6.0. While you will not have Arc Graphics working on H2'2022 Linux distributions, aside from any distros that may decide to back-port, the i915 DRM kernel changes and ship with a bleeding-edge Mesa.
