Compiling kernel 3.4 on debian wheezy

sudo apt-get install kernel-package fakeroot build-essential

mkdir ~/tmp
cd ~/tmp
wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.4.tar.bz2
tar xvf linux-3.4.tar.bz2
cd linux-3.4/
cat /boot/config-`uname -r`>.config
make oldconfig

If your current kernel is 3.3.5 the questions that await are given at the bottom of this post with links to descriptions of the different options. As usual, if in doubt, just hit enter.

make-kpkg clean

Building takes ages (depending on number of cores committed), so don't launch it at 4 pm on a Friday if you need to shut down your computer before going home... As usual, use the -jX switch for parallel builds, where X is the number of cores+1 (i.e. 4 cores => -j5)

The following command goes on a single line
time fakeroot make-kpkg -j5 --initrd --revision=3.4.0 --append-to-version=-amd64 kernel_image kernel_headers

Once the build is done, move the .deb files out of the way and to your linux-3.4 directory for safe-keeping
 mv ../*3.4.0*.deb .
sudo dpkg -i *.deb
