i have created a repo with the version for you here: andersrh/cachyos-kernel-6.7.0 Copr
It should be an exact build of the state from 6.7.0 with patches as they were at that point in time.
beware you may need to disable this official repo in order to install the older version from my repo, since dnf will choose the newest available version.
Itās probably a dnf thing.
I updated from 6.9.2 to 6.9.3, but after I installed/reinstall manually some packages related to kernel-cachyos-6.9.3-cb1.0 (devel, devel-matched etc) the kernel was removed from /boot despite being considered installed by dnf. I was running dracut as I usually do after an update for plymouth to work on external monitor on NVIDIA drivers, and it showed a message that wasnāt finding files for that kernel.
The LTO I just installed since this weird thing happened.
Try to remove cachyos kernel with rpm -e --nodeps $(rpm -qa | grep cachyos) and reinstall it with sudo dnf install kernel-cachyos-devel-matched or sudo dnf install kernel-cachyos-lto-devel-matched. Also you shouldnt have both lto and normal kernels installed since akmod build for nvidia will fail on gcc built kernel if lto repo is enabled.
Hello, thank you very much for providing RT kernels for Fedora. Results in the audio field of applications are awesome.
Is there any chance that you will move the RT kernel to 6.10 which seems to be a new reference for this ?
Thank you.
Iām gonna ramble a bit.
It seems that the change to Tuned on Fedora 41 Beta is causing incompatibility problems on my machine. Not really sure if itās just with Negativo17ās NVIDIA drivers or if itās the drivers + if itās kernel-cachyos and kernel-cachyos-addons. It also happened when I decided to test tuned on Fedora 40.
Had weird behaviors on Fedora 40 when I decided testing Tuned and now on Fedora 41 Beta had the same issues (slugish terminals, browsers; browsers no fully loading pages etc, extremelly slow DNF, probably because of the slugish terminals). Switching back to power profiles daemon solved it.
For a ā¦ conformant test, I removed kernel-cachyos and the addons plus negativo17ās driver, and switched to RPMFusion and Iām keeping just Fedoraās kernel for now to check if I get those problems again.
Now Fedoraās kernels are also installing two additional packages: kernel-tools and kernel-tools-libs. Described as āAssortment of tools for the Linux kernelā and āLibraries for kernel-toolsā respectively.
It seems that the problems I had with Tuned was DNF didnāt update what is needed for it to work. (probaly/maybe/in theory). I have to test kernel-cachyos with my current fresh install of Fedora 41 Beta to check.
On my backups from my Fedora 41 beta upgrade form Fedora 40 the kernel args/cmdline has a variable called $tuned_params. Which is not present on the system that was upgrade but is present on my fresh install. There is also a $tuned_initrd that Iām not sure how to search o my backups to check it was also present or not.
I did one more test. Iām not sure, have to test more, but have to be on a different installation, if itās a combination of using CachyOSās kernel and Negativo17ās NVIDIA drivers or just chaning the kernel
I installed Fedora 40 (original ISO) on my external USB SSD. worth noting I used DNF4 not DNF5 to upgrade.
after upgrading and installing RPMFusionās NVIDIA dirvers, it did not add the nvidia.drm=1 line to GRUB, because things were really slughish. Note: NVIDIA driver 555 for F40 seems to have problems because the system still feels worth than with driver 560;
after upgrading the full system to the latest available for F40 and upgrading to F41 Beta it did not add the tuned related variables to the grub file/kernel lines.
Fedora 40 fully upgrade before upgrading to Fedora 41
I was about to continue to test, installed kernel cachyos, not uksmd yet. Restarted after a while with no problems I loock at the sevices, and the upgrade didnāt replace power-profiles-daemon with tuned.

On this new test installation, after swapping to tuned with dnf and with the current Cachyos kernel version and with or without the uksmd addon, I havenāt notice any of the problems.

I even removed RPMFusionās NVIDIA drivers and installed from Negativo17ās and notice no problems yet. Worth noting that Negativoās is shipping a beta driver 565.57.01, but even with that one notice no problems yet.
So besides not updating the kernel parameters and not installing tuned and replacing power-profiles-daemon, the problems seem to be gone with the current updates
Hi, I appreciate the kernel build and all the work the Cachy team puts in! Can you confirm if this has the t2 patches included or not? I assume it does but there seemed to be a few bugs i did not encounter in the full cachyos experience or the latest fedora t2 image. If youāve got the t2 patches in, do you care to take any bug reports directly if they seem specific to your kernel build, or would it be better for me to leave bugs info somewhere else? Itās not the end of the world, just prefer your kernel to the default. Thanks!
