So you have three options to get the newest protection against spectre/meltdown
1.Try the 4.15.0-1-amd64-mx kernel without the boot parameter,just for to make it sure.(But I think it will crash during idle)
2. Stay with the antix-kernels and download the newest 4.15.5-antix.1-amd64-smp with synaptic.It's not in the Package-Installer(only 4.15.3,I don't know why) and use the bootparameter.
Code: Select all
$ sudo cat /boot/config-4.15.5-antix.1-amd64-smp | grep CONFIG_RCU_NOCB_CPU
CONFIG_RCU_NOCB_CPU=y
3.Try the liqourix-kernel -4.15.0-6.1-liquorix-amd64, whis is in the Package-Installer, with the boot-parameter. It also has the flag set to yes.
Code: Select all
$ sudo cat /boot/config-4.15.0-6.1-liquorix-amd64 | grep CONFIG_RCU_NOCB_CPU
CONFIG_RCU_NOCB_CPU=y

Question: How to add: rcu_nocbs=0-7 since I am already installed with 4.15.5-antix
- For 8-threads Ryzen (1500X, 1500, 1400): rcu_nocbs=0-7

You can add the boot parameter with the command line like caprea showed.
I used the MX grub manager (I think that is the name, it is in the MX ---> system menu). You have to supply root PW.
In the center tab, it shows the boot parameters, I had some kind of zsynch (?) parameter, so I typed one space then added the
rcu_nocbs=0-7 (In my case it was 0-11)
Apply, update grub, and reboot.
The 4.15.3 has been absolutely stable since I added that.

I am trying to get the 4.15.5 to run. I installed with synaptic, headers and image. I ran the dpkg reconfigure, update-grub.
The reconfigure did build an nvidia for the 4.15.5.
Despite this I booted to a black screen with a blinking cursor. I could not startx.
I have to look at old posts, maybe caprea had a trick to the install the linux image after the dkgk reconfigure. But that is a separate post and problem.

Boot into the 4.15.5-antix-kernel
type in terminal
The output will probably look like this for your cpu
rcu_nocbs=0-7
Whatever comes out, this you have to add to your grub-line
Then type in terminal
This will open the grub-file with the following lines
Code: Select all
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="vga=791 quiet"
GRUB_CMDLINE_LINUX=""
Add the output of the above command rcu_nocbs=0-7 (or whatever) to the GRUB_CMDLINE_LINUX_DEFAULT - line
should look like this
Code: Select all
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="vga=791 quiet rcu_nocbs=0-7"
GRUB_CMDLINE_LINUX=""
Close the file and save it.
Then
Reboot
Look if the parameter is active with
That's it!
Test if your system is stable, leave it in idle or whatever.
The rcu_nocbs=x-x bootparameter just replaces the CONFIG_RCU_NOCB_CPU_ALL=y configuration, which was active on the working 4.10-kernels
and was removed sometime later during kernel-developement.Maybe it's a bug for the ryzen.
If that should not work for you, the bootparameter can easily be removed again.
Give it a try!

caprea,
Thanks for the hand holding explanation, to let me make this change. All should be well again.
I do not have a motherboard temperature, and know my 2007 video card is running warm but system was up and running all night long seeding AntiX-17 and Mx-17. I made final change via your instructions today and will hope system can run 24/7 for a few weeks without more Kernel/Ryzen cutting edge hiccups.

entropyfoe,
I am using AntiX 17, and used: Applications> system tools> Package installer> and the Kernel drop down menu to choose the 4.15.5 version.
I do not have a Nvidia card, to complicate the kernel change as the 7 year old Radeon video card boots to a graphical screen without any additional manipulations.
I always purchase CPU with the video built in, last few years anyway, but wanted a faster CPU this time around, and needed to use a older Video card to keep the build cost within my pocketbook outlay so I did not alarm my lady. The crypto miners have taken Video cards to astronomical pricing heights, but I am still occasionally searching craigslist for a newer Video Card.

namida12, let us know how it went for you with the bootoption.
Also it seems for some boards bios updates finally appear that solve the problem.

Still smiling, and wondering should I upgrade to the newer version. Is new version is running the 4.15.9 kernel-antix. Does that have the boot fix?
Since I seed MX, and Antix are there new 17.1 torrent I did not see?

Ah, I see Uptime: 9 days, cool !
4.15.9 kernel-antix is OK. CONFIG_RCU_NOCB_CPU=y
but not the default on antiX17.1

Waiting for newer AntiX 4.16 version to see if there are any improvements...
Had a Asus 24 inch Monitor die, and the left DVI connector while looking at the face plate on my AMD RV670 [Radeon HD 3690/3850] video card this week. Switched to the right DVI connector on the video card and it is working with replacement Acer 23 inch screen. The Asus monitor will not work with VGA, DVI or HDMI connectors. Maybe a switch replacement daughter card might be the fix, not certain yet...
