Install newer kernel version

1. Enable ELRepo

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
dnf install https://www.elrepo.org/elrepo-release-9.el9.elrepo.noarch.rpm

2. Install latest mainline stable kernel

dnf --enablerepo=elrepo-kernel install kernel-ml 

3. Verify Installed Kernel Version

grubby --default-kernel

If kernel version shows newer kernel , reboot

After reboot, verify newer kernel was installed

uname -sr  

Update kernel headers & dev tools to newer kernel version

If not done already , install following packages

dnf groupinstall "Development Tools"
# or install packages separately 
dnf install kernel-headers kernel-devel

1. Check kernel-devel & kernel-headers package matches kernel version

rpm -qa | grep -E "kernel-devel|kernel-headers"

If version doesn’t match current kernel version , proceed to step 2

2. Update kernel headers and development tools

# Install development tools 
dnf groupinstall
