Install Kernel 2.6.39 RC4 on Ubuntu 11.04

Recently I need to upgrade Ubuntu kernel version. I tried to do same with kernel-ppa. But it was not working. So I need to install it manually.

I am using 32bit machine and my current kernel version is :

uname -r

2.6.38-8-generic

To update the version to 2.6.39 RC4 download the kernel first:

mkdir /tmp/kernel
cd /tmp/kernel
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.39-rc4-natty/linux-image-2.6.39-020639rc4-generic_2.6.39-020639rc4.201104191410_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.39-rc4-natty/linux-headers-2.6.39-020639rc4_2.6.39-020639rc4.201104191410_all.deb

Now we need to install kernel-image as well as kernel-headers

cd /tmp/kernel
sudo dpkg -i *

Now we need to reboot our machine to update the version:

sudo init 6

While rebooting choose kernel 2.6.39-020639rc4. Once the reboot confirm the kernel version by running

uname -r

2.6.39-020639rc4-generic

For 64bit machine you can download file from below links:
linux-image-2.6.39-rc4-amd64.deb
linux-headers-2.6.39-rc4-all.deb
