Update kernel 4.0.1 in debian 8 jessie from linux-4.0.1.tar.xz file

Kernel version 4.0.1 was released few days before Debian 8 Jessie was released. Jessie is not packed with kernel 4.0.1 (stable). So updating is a cool idea.

Step 1: Download the kernel 4.0.1 tar.xz file from www.kernel.org and copy in Desktop

Installation Process:

Step 2: Go to Desktop directory

cd Desktop

Step 3: Run unxz tool

unxz linux-4.0.1.tar.xz

Step 4: Unzip Tar

tar xvf linux-4.0.1.tar

Step 5: Open Kernel Directory

cd linux-4.0.1

Step 6: For a fresh installation, run

make menuconfig

Note: This might give an error message. Thus necessary library package needs to be installed.

apt-get install libncurses5-dev

Step 7: Run step 6

if it didn't work install all necessary packages, with

sudo apt-get install fakeroot build-essential kernel-package ncurses-bin ncurses-dev

Step 8: Run step 6

Blue screen appears. Check whether everything is OK. When finished - use tab to select "Exit" or "Cancel"

Step 9:

When it will exit you will see output in the terminal as in the end.

root@sandipn:/home/sandipn/kernel/linux-4.0.1# make menuconfig

HOSTCC .. .. .. .. .. ..

.. .. .. .. .. .. .. .. .. .

.. .. .. .. .. .. .. .. .. . . . . .

# configuration written to .config

#

*** End of the configuration.

*** Execute 'make' to start the build or try 'make help'.

This isn't very much important. Only important one is the line 

#configuration written to .config

Step 10: Clean unwanted files

make-kpkg clean

Step 11: Bild a Debian package (.deb extension) for dpkg tool,

fakeroot make-kpkg -j6 --initrd --revision=4.0.1 --append-to-version=-amd64 kernel_image kernel_headers

Compile:

time fakeroot make-kpkg -j6 --initrdevision=4.0.1 --append-to-version=-amd64 kernel_image kernel_headers

Step 12: Terminal starts to scroll with the command above.

.. .. .. .. ..           

CC [M] fs/ext2/acl.o

CC [M] fs/ext2/xattr_security.o

.. .. .. ..

so on.

Step 13: At the end, install .deb package and reboot the system.

Step 14: Select new kernel from grub.

You will have successfully installed kernel 4.0.1
