Kernel Upgrade - Best practice

Bazzite
1

Hi,

I am running latest Bazzite, which has the 6.17.7 kernel. For newest rocm version i need 6.18.4 at least on my hardware. (Strix Halo with lemonade-server.ai , i want to run some image generation)

As far as i understand Bazzite branches off of Fedora Silverblue, so currently F43, which dates back to october 2025. Is it possible to update the kernel? I saw some rpm-ostree commands.

approach 1:

Something like this sudo rpm-ostree override replace https://koji.fedoraproject.org/koji/buildinfo?buildID=2951941 with the url pointing to kernel version 6.19.6. But it had some issues with the current version so it did not progress. I dont know if i need to say rpm-ostree should remove the current kernel first.

I think with this approach i will have to maintain the kernel myself until i reverse it. which also would require a new command…

approach 2

is there some kind of beta version or newer version? in bluefin i am already on 6.18.x in comparison, since i can rebase on some less stable but newer version.

I read that Silverblue 44 Beta was just released today. This would be an option i.e. for a bazzite beta version.

Do you absolutely have to stay with Bazzite? Could you rebase (at least temporarily) into Aurora? It looks like Aurora’s running kernel 6.18.13 (or is it 6.18.10 – it looks like they might have downgraded the kernel?):

I think this tells how to rebase from Bazzite to Aurora near the bottom:

Aurora and Bazzite are not the same beast.

You will need to wait until Bazzite switches to a new kernel, which would be based on the 6.19 branch.

There is no easy way to manually update the kernel, and if you would do it. You would loose all the extra patches etc that are on the current bazzite kernel.

stable uses the coreOS kernel which is always gated behind what Fedora has.

If you want the newest one from Fedora, you will need to use aurora:latest stream

Thanks a lot!

I guess right now the best option for me is to be patient.
If this issue comes up more often, i might need to consider changing to another distro. Lets see. But pretty nice to be able to switch at least distros even if it means some features might not work.

Thanks!
