Kernel Fix

Installing custom kernel with sub packages

• Check all packages installed and available

$ sudo dnf list kernel --showduplicates
$ sudo dnf list kernel-headers --showduplicates
$ sudo dnf list kernel-devel --showduplicates

• Download RPMs manually from Fedora Koji.

  • kernel-6.12.4-200.fc41.x86_64.rpm
  • kernel-core-6.12.4-200.fc41.x86_64.rpm
  • kernel-modules-6.12.4-200.fc41.x86_64.rpm
  • kernel-modules-core-6.12.4-200.fc41.x86_64.rpm
  • kernel-devel-6.12.4-200.fc41.x86_64.rpm
  • kernel-headers-6.12.4-200.fc41.x86_64.rpm

• Install packages and verify

$ sudo rpm -Uvh --oldpackage --nodeps kernel-*.rpm

• Set the default kernel

$ sudo grubby --set-default /boot/vmlinuz-6.12.4-200.fc41.x86_64

• Reboot (`sudo reboot)

Exclude kernel from update

• Temporary skip

$ sudo dnf update --exclude=kernel*

• update /etc/dnf/dnf.conf

[main]
...
exclude=kernel-*

KVM issue:

$ lsmod | grep kvm

# Unload KVM Modules Temporarily
$ sudo rmmod kvm_intel kvm

# Load KVM back
$ sudo modprobe kvm_intel

• Update vboxconfig

$ sudo /sbin/vboxconfig
