Yes, now it works, thank you :)

Sure, I can try, if you give me instructions to follow.
This is my current kernel:
```
$ uname -a
Linux fedora 6.16.7-200.fc42.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Sep 11
17:46:54 UTC 2025 x86_64 GNU/Linux
```
After installing, do I wait until Fedora catches up to the new version
and then reinstall the kernel from dnf?
Do I need to watch out when doing `dnf update` that it won't override
the kernel?

Thanks,
Yinon
