How to apply the xenomai kernel patch on debian?

Question

I've been trying to install xenomai on debian and I'm confused about all the version numbers. I'm on Debian 6 (Linux debian 2.6.32-5-686 #1 SMP Tue May 13 16:33:32 UTC 2014 i686 GNU/Linux)

Steps I followed,

1. installed the linux-patch-xenomai from apt via aptitude install linux-patch-xenomai
2. then according to /usr/share/doc/linux-patch-xenomai/README.Debian I need the kernel source. I got the kernel source via aptitude install linux-source-2.6
3. expand the source tree tar -xvf linux-source-2.6.32.tar.bz2 in /usr/src/

4. then apply the patch as explained in the above README.Debian by /usr/src/kernel-patches/i386/apply/xenomai which fails

   1 out of 4 hunks FAILED -- saving rejects to file arch/x86/kernel/process_64.c.rej
   1 out of 6 hunks FAILED -- saving rejects to file arch/x86/mm/fault.c.rej
   1 out of 15 hunks FAILED -- saving rejects to file kernel/sched.c.rej
   1 out of 1 hunk FAILED -- saving rejects to file kernel/signal.c.rej
   

Why is this failing even though the above README.Debian states This is intended for vanilla and Debian kernel sources? I know debian 6 is eol but any help is appreciated.

How to apply the xenomai kernel patch on debian?

You can get the required steps to apply the xenomai patch on the 2.6* kernel version from the README.INSTALL :

cd /usr/src/
wget http://download.gna.org/xenomai/stable/xenomai-2.5.6.tar.bz2
tar xvf xenomai-2.5.6.tar.bz2
cat /xenomai-2.5.6/README.INSTALL

From the _ 1.1 Preparing the target kernel _ the syntax is:

scripts/prepare-kernel.sh --linux=<linux-srctree> [--adeos=<adeos-patch>] [--arch=<target-arch>]

The adeos-patch can be downloaded from here

The kernel source can be found here

There is an example:

cd /usr/src
wget http://download.gna.org/xenomai/stable/xenomai-2.5.6.tar.bz2
tar xvf xenomai-2.5.6.tar.bz2

wget http://download.gna.org/adeos/patches/v2.6/x86/adeos-ipipe-2.6.38.8-x86-2.11-03.patch

wget https://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.32.tar.gz
tar xvf linux-2.6.32.tar.gz

cd /xenomai-2.5.6/scripts

./prepare-kernel.sh --linux=../../linux-2.6.32/ --adeos=../../adeos-ipipe-2.6.38.8-x86-2.11-03.patch --arch=`uname -m`

Edit

The Kernel and the adeos patch should have the same version numbers , the old versions of adeos can be found here
