All Meltdown Patched Kernels crash this AntiX Ryzen system. I read someplace that AMD does not need meltdown patch. Is that the problem with the newer kernels and this system?

I can run the default Kernel and it never crashes, anything I download marked meltdown patched does not continue to run.

namida,
For me the only thing that is totally stable is the antix 4.10 (non patched) and 4.9.77-antix.
The 4.9.77 is patched
see https://www.antixforum.com/spectre-and- ... -upgrades/

4.14, 4.12, I think there was a 4.13 for MX. All crash 1 -2 times a day.

Lately I have better luck with the MX Package installer,
And the 4.9.77 is in there.
it does more than synaptic, even if you run the dkms reconfig.
You have an amd card, and I depend on the nvidia driver getting set up properly.
So it might be different.

I really doubt that it's the KPTI mitigation. I even believe that the kernel detects your AMD cpu and doesn't use it in your case.

Yup, that was the party line, Linus said linux would not apply meltdown patches to the amd chips. Where as Microsoft had to go with Intel, and pretend that the OS couldn't tell what processor it had, and so the patch would be applied to both Intel and AMD systems. (slowing Intel's competition as much as themselves)

For me the crashes were before the patches. The syslogs show or mean little to me, just a reboot.

I have great hopes for 4.15, it will have the patches baked in, and it is written that maybe the Ryzen temperature monitoring will be working.
I would think they test with my common Ryzen board and cpu.

But aside from the temp monitoring, I don't need the latest kernel, as long as the devices on the system all work. This 4.9.77 antix can last a good long while while the bugs get out of 4.15.

How are kernels selected to appear in the kernel section of the Package Installer?

The developers decide what will kernels will be installed in the package installer scripts. In some cases, like the Liquorix kernel, it goes for the latest available one.

Well I am thankful that they decided to include the 4.9.77, as it is the only one stable for me and patched.

I'm running a 4.15.0-ryzen2 Kernel. I compiled it myself and paired it with Nvidia 390.25 driver. Download it from kernel.org, obviously

THIS WORKS ON MX 17

Here is what I did to compile the 4.15 Kernel. NOTE: I added a recovery Kernel option so in the boot menu I can boot straight into the CLI (user level 3, I think.. no GUI) and then manually install Nvidia. I do this because I add some optimizations to the Nvidia driver to make it compile a faster module!

tar -xvf kernelxxxx
cd kernelxxxxx
make oldconfig (this doesn't seem to work on MX Linux until you compile your own Kernel, but maybe it will work for you)
make xconfig (this isn't fun. It's tedius)

Now, install all your devices and activate them as much as possible. Webcam, open OBS or whatever. Mount flash drives, etc.

make localmodconfig <-- this will remove unnecessary stuffs, and it will add M to modules loaded but it isn't flawless so go back to fix things with make xconfig
make xconfig <-- Check vfat, NTFS, NTFS write because they were set to N after the last command you ran

sudo fakeroot sudo make -j`getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-ryzenz KDEB_PKGVERSION=1 CFLAGS="-O3 -march=native" CPPFLAGS="-O3 -march=native" CXXFLAGS="-O3 -march=native" X_CFLAGS="-O3 -march=native"

sudo dpkg -i *headers*.deb
sudo dpkg -i *image*.deb

Now, to test it out. Just boot like normal. I usually add a recovery mode Kernel boot option in order to install Nvidia driver manually. It should work and it should be really fast- fully optimized for Ryzen.

It would help if you posted/attached the resulting .config file

Can you make a successful snapshot iso using your kernel?

Posted: **Sat Feb 10, 2018 7:10 am**

mmm, 4.14.14 kernel, isn't this back dated??
liquorix just releases 4.14.18 kernel on 9/feb, why dun u try it??

Ummm, help me out here. How do I do this with MX 17? I'm new to MX Linux- and it is the best Linux ever! I use to use Ubuntu Customizer until that Italian guy stopped maintaining it. :-(

The process is very easy until you get to the make xconfig part but you have some help with make localmodconfig. Xconfig is where you can fine tune all you want. I add extra sound buffers, NTFS support, I remove ALL debugging that I possibly can remove, ALL profiling, and I tune it for low latency.
