Compile latest Linux kernel for Debian
Modified:
Created:
Install needed packages
apt-get install fakeroot kernel-package libncurses5-dev
Download latest Kernel source
As of this writing, the latest source is 4.3.3
wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.3.3.tar.xz
export KVERSION=4.3.3
tar xvJf linux-$KVERSION.tar.xz
Start configuring
cd linux-$KVERSION
Get current config
cp /boot/config-`uname –r` .config
Start menuconfig and change the stuff you want to:
make menuconfig
Clean:
make-kpkg clean
Building
Export the wanted concurrency (number of cores + 1) and build a Debian package of the kernel.
export CONCURRENCY_LEVEL=5
fakeroot make-kpkg --append-to-version "-customkernel" --revision "1" --initrd kernel_image kernel_headers
When this command is complete, we will have two dpkg files, one for the kernel and one for headers. The great thing about this is that we can just install them and it will fix grub for us.
dpkg -i linux-headers-$KVERSION-customkernel_1_amd64.deb linux-image-$KVERSION-customkernel_1_amd64.deb
Cleaning
Remove everything we do not need anymore:
cd ~
rm -f linux-$KVERSION.tar.xz
rm -rf linux-$KVERSION
rm -f linux-headers-$KVERSION-customkernel_1_amd64.deb linux-image-$KVERSION-customkernel_1_amd64.deb
Remove a custom kernel
To remove a kernel that we are not using, or that does not work just uninstall it.
apt-get remove linux-image-$KVERSION-customkernel linux-headers-$KVERSION-customkernel
