Upgrading Debian Kernel

I was having some problems with my newest ethernet NIC Atheros AR8151-B in Kernel 2.6.32.xx in Debian Squezee 6.0.5. I have found a usefull post about this.

To find out what version of kernel you are using:

uname -a

it should say something like Linux debian 2.6.32.xx #1 SMP Fri Jun 29 20:42:29 UTC 2012 x86_64 GNU/Linux

Upgrading Debian Kernel

1. Edit sources.list file and add the following line:

deb http://backports.debian.org/debian-backports squeeze-backports main

2. Update the repositories list

apt-get update

3. Find the name of the newest linux-image:

apt-cache search linux-image

you should see something like this linux-image-3.2.0-0.bpo.2-amd64 - Linux 3.2 for 64-bit PCs. Your version will certainly will be different.

4. Install the latest Kernel found (it will automatically install the required dependencies)

apt-get install -t squeeze-backports linux-image-3.2.0-0.bpo.2-amd64

After a successfull install, reboot. You should see 2 different versions of Debian on Grub Interface.
