Do you have a source for this please?


There is a changelog in /usr/share/doc/linux-image* for every kernel installed, are you even using debian anymore? Your posts in the past have been really excellent, but lately you seem a little off balance with regard to debian.

I haven't used Debian myself for several years, I prefer less complicated operating systems :)

I do maintain the family laptop though and that's always run Debian stable, I did enable unattended-upgrades once stretch rolled out and I hardly ever touch the box these days. It's wonderful :D

Hmmm...just did a rebuild of the backported MX 17 4.14.12-2 kernels overnight on generic Stretch pbuilders to add the Ryzen amd64-microcode patch and have the headers pull in libelf-dev, which is still not fixed in Sid. Headaches: some report the Spectre-mitigated 384.111 Nvidia driver just added to stretch-backports won't build on that kernel, but I was able to do so and use it on my Optimus laptop. They had no issue with the Liquorix kernel, though. That kernel isn't in stretch-backports, though.

If that's true about older kernels, are standard Jessie users up the creek with all 32-bit users now?
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Krita 3.3.3, Pale Moon 27.7.2, Yacreader 9.0, Calligra 3.1, VLC 3.0.0, Firefox 58.0.2, OBS-Studio 21.0.2

Well, I wouldn't say that 32-bit users were "up the creek" because the patch developer has committed to work on it, albeit without a timeframe.

Also, the KAISER fix appears to have been used for all kernels not of the 4.14-series so that would mean stretch, jessie and wheezy.

The KAISER patch was originally designed as a strengthened form of KASLR[1] that incorporated more of Grsecurity's work but it does not offer the same level of protection as KPTI, so again I think "up the creek" is perhaps putting it a little strongly.

Skyfall and Solace are two speculative attacks based on the work highlighted by Meltdown and Spectre.

Has your equipment all had the Spectre/Meltdown patches applied? :roll:

If so, I don't think you can claim "fast" any longer. :lol:
