[SOLVED] linux-image-6.* / Chimaera

jue-gen · 2022-11-22 16:46:29

Hello to each other,
I have a question:
I have installed the meta package linux-image-amd64 and with it currently linux-image-5.10.0-19-amd64 on Chimaera. Now I see that linux-image-6.* is also installable. Is there anything to consider when I install that?
Best regards

You will need to enable backports in your sources.list. Then you are able to install the latest kernel from backports on Chimaera. When you are sure its working fine you should consider installing linux-image-amd64 from backports to receive upgrades from there. Side effect: you won't get updates of the 5.10 line of kernels any more.

Where do you see this?

Can we see the output of

apt policy

If you're using the stable release then the backports & development repositories shouldn't be available unless you've added them. What have you changed in your sources, exactly?

If the kernel provided by the stable release supports your hardware then changing to the backported version will probably only introduce new bugs & regressions. Also bear in mind that the backported kernel is delayed by 10-14 days compared to unstable and will fall further behind once the package freeze starts in January. Running an outdated kernel is unwise. The stable kernel is kept up to date with the relevant upstream LTS branch and so should be "safer".

Yes, linux-image-6.0.0.0 and corresponding headers are now available in Chimaera backports.

Do you have newer hardware that actually needs anything later than the stable 5.10 kernel (which is still being updated with security patches)?

In my case I did update from 5.10 to 5.15 when I updated my processor and motherboard to ones that weren't fully covered by 5.10 (AMD 5600G and a new sensors chip on my B550 motherboard) however I found that subsequent kernels 5.18 and 5.19 contained regressions which caused certain programs I use to glitch so I reverted to 5.15.

I might try 6.0 but it's quite possible the regressions are still there and I'll have to revert.

On my ThinkPad I leave the stable kernel. However, I'm getting another machine with an AMD Ryzen 7 5700G.

Yes, that is also my concern. I'm getting a computer with an AMD Ryzen 7 5700G and I'm worried about an optimal installation.

Did you add the backports repositories yourself? They seem to be correctly configured at any rate.

The Ryzen 5700G was released 2021-04-13 & Debian bullseye was released 2021-08-14 so the CPU itself might be fine with kernel 5.10. I have a laptop running a 5850U and I don't recall having any CPU problems with the stable kernel. The amd64-microcode package in stable is too old though and you will probably get better support with a newer kernel.

Yes, I have compiled the sources.list like this:

This sounds good " ... so the CPU itself might be fine with kernel 5.10."
I'll just have to try it out. If anyone has any recommendations for the AMD Ryzen 7 5700G and the kernels, I'd love to hear them.

Marjorie · 2022-11-22 22:24:52

Agree, the CPU on my 5600G worked fine with 5.10, the issues I had were in support for the integrated GPU. This was improved with new GPU commits from AMD in 5:15.
I also have a nct6687-isa-0a20 fans sensor on the MSI AMD B550 MPG Gaming Plus Motherboard that I needed the 5.15 kernel headers so I could compile in its kernel module.
On my system upgrading to kernels 5.18 and 5.19 caused graphical glitching with Signal Desktop and Zoom and issues with getting reliable hibernation.

Ok, thanks everyone, then I'll install Devuan on this new machine with the AMD Ryzen 7 5700G and hope it all fits. So far I've only ever installed on relatively old Lenovo ThinkPads and desktops.
If Chimaera becomes Daedalus, yes probably linux-image-6.* comes with it.
On my ThinkPad I leave the 5.10 kernel at the moment.
Best regards
