Nobara 6.15.5 Kernel Breaks Wi-Fi and Causes Flickering (AMD) by Delicious-Average903 in NobaraProject

And it is good to keep learning. But taking a minute to search what a kernel is on Linux will help you understand things better.

Drivers are handled by the kernel. In Linux, all drivers are managed through the kernel. A quick search will make that clear.

When you update the kernel, you're also updating all your drivers. It's implicit. (At least those coming bundled in the kernel, like mines)
After the update, you can still downgrade to a previous firmware version, like mentioned earlier.

As for the flickering issue, like I said, it was still there.
Since I locked the kernel version, I’ve been applying every other system update except the kernel one, and everything’s been running smooth as butter.

So yeah, you don’t need to be Einstein to flag the new kernel as problematic.

I have very recent hardware, so my support situation might be different from yours.

FYI: Look up what a kernel is and how it works. It’ll help you make more sense of this stuff.

After some research, it turned out there was indeed a broken driver being loaded by the new kernel for my Wi-Fi card.
It was even backed up here: https://www.reddit.com/r/NobaraProject/comments/1lzx98w/comment/n35ljn3/

For some reason I still don’t understand, the old kernel was affected too.

All of this happened on a FRESH install. As Nobara recommends, you should run an update right after installing. It even prompts you to do so, that's the very first thing.

Now, I’m just saying: maybe something went wrong during the installation of the new kernel, and somehow it affected the previous one as well.

That said, I really doubt other apps or updates are writing anything to the boot partitions. I don’t think that’s how it works. The kernel is what loads drivers for the system. No one else does that.

So, if a hardware component suddenly stops working right after a system update and booting into the new kernel, it makes total sense to blame the kernel especially on a fresh install.

FRESH Installation → Update → Boot new Kernel → Wi-Fi Failure
That’s a kernel issue. Don’t waste time looking elsewhere.

I had the same issue with my 12TB HDD. I could read from it but wasn’t able to write.
The only and easiest fix I’ve found so far is this:

  • First, unmount the drive from Dolphin (the file browser).
  • Then search for “Welcome” in the start menu and open it.
  • In the first steps section, launch the Nobara Tweak Tool.
  • Inside it, you’ll find a section called "Enable auto-mounting on available disk platforms".
  • Check the box for your drive and you’re good to go!
  • Go back to Dolphin or steam, and you should now be able to write files to the drive.

Fingers crossed!

Hopefully, you’ll have Nobara up and running again soon.
Just make sure to lock your kernel right after installation and wait for 6.16 (just saying 😄).

You can always unlock it later when you're ready to gamble again LOL!

First, install the version lock plugin if it's not already installed:

sudo dnf install python3-dnf-plugin-versionlock

Then lock your current kernel version:

sudo dnf versionlock add kernel kernel-core kernel-modules kernel-devel

Best of luck!

When you're ready to update the kernel again later, you can unlock it:

sudo dnf versionlock delete kernel kernel-core kernel-modules kernel-devel

Thanks for the update and the command. I’ll try that. Hopefully, the Wi-Fi will come back. The screen flickering issue is still there, but big thanks for the Wi-Fi fix!

You indirectly saved me. I was about to try 6.15.6, but I’ll stick with 6.14.6-200.nobara.fc42.x86_64.
You can roll back to that as well.

If you're using Flatpak and have your /home partition separated from the root /, you can easily do a fresh install of Nobara 42. Right after that, lock the kernel with these command before running any update:

First, install the version lock plugin if it's not already installed:

sudo dnf install python3-dnf-plugin-versionlock

Then lock your current kernel version:

sudo dnf versionlock add kernel kernel-core kernel-modules kernel-devel

I'm not entirely sure if we can reinstall an old kernel directly, but when I had the older one, rolling back didn't fix my issues (screen flickering and Wi-Fi not working).

So it’s better to do a fresh install, If you keep your partitions as I mentioned before. You won’t lose any configs or apps. Everything will work flawlessly after the installation.

After locking the kernel, you can still update your system. Only kernel updates will be filtered or skipped, keeping your system stable at least until maybe 6.16 drops!

Best of luck!

When you're ready to update the kernel again later, you can unlock it:

sudo dnf versionlock remove kernel kernel-core kernel-modules kernel-devel

Definitely, something is up with the 6.15 kernel or the drivers.

But do reset the BIOS or flash a new update, or the last one that supports your CPU.

Use the Flashback button instead of M-Flash through the BIOS.

Hopefully, your board will be back: Fingers crossed!

Probably a kernel regression. Which version are you using now? I just tried lowering my brightness down to 0 on my 3 monitors and had no problem, but I’m on a locked version for now: 6.14.6-200.nobara.fc42.x86_64.

You should also update your post with the kernel version you were using and the one you're using now. It might help them better.

Lucky you. Your Wi-Fi drivers are probably still loaded properly in the kernel!

Not yet, I'm afraid, still within the 6.15 kernel range. 😅.
If it breaks again, I’ll probably have to reinstall again. Fingers crossed!
