Linux 6.3-rc2

It's another Sunday afternoon. which must mean another rc release.


This one looks fairly normal, although if you look at the diffs, they
are dominated by the removal of a staging driver (r8188eu) that has
been superceded by a proper driver. That removal itself is 90% of the
diffs.


But if you filter that out, it all looks normal. Still more than two
thirds in drivers, but hey, that's pretty normal. It's mostly gpu and
networking as usual, but there's various other driver fixes in there
too.


Outside of that regular driver noise (and the unusual driver removal
noise) it's a little bit of everything: core networking, arch fixes,
documentation, filesystems (btrfs, xfs, and ext4, but also some core
vfs fixes). And io_uring and some tooling.


The full shortlog is appended, for the adventurous souls that want to
get that kind of details. The release feels fairly normal so far, but
it's early days. Please keep testing and reporting any issues,

• New Linux kernel patches introduce workaround for system stuttering on AMD systems

  Linux kernel maintainers have backported a workaround to Linux 6.1.19 and Linux 6.2.6 from Linux 6.3-rc2 to fix system stuttering on some AMD machines. According to Phoronix, the updates were backported to older Linux 6 releases on Monday morning following the release of workaround on Linux 6.3-rc2 on Sunday.

  The stuttering issue was noted by users with AMD Ryzen systems that were using outdated fTPM firmware. It only became an issue for Linux users after AMD’s fTPM hardware random number generator started being used by default. If you run a distro such as Ubuntu 22.04 LTS, you probably won’t be suffering from the issue because it uses the older Linux 5.19 kernel out-of-the-box.
