Xen users - Jun 2007 - How do I upgrade from 2.6.18 to 2.6.18-4?

Hi,

How do I upgrade from 2.6.18 to 2.6.18-4?

I have tried this
download http://www.kernel.org/pub/linux/kernel/v2.6/patch-2.6.18.4.bz2

cd /usr/src/xen-3.1.0-src/linux-2.6.18-xen
patch -p1 < patch-2.6.18.4

This gave me two hunk errors.
1. patching file Makefile
Hunk #1 FAILED at 1.
Hunk #2 succeeded at 895 (offset 1 line).
Hunk #3 succeeded at 1080 (offset 1 line).
1 out of 3 hunks FAILED -- saving rejects to file Makefile.rej

                if (unlikely(!nskb))
                        goto err;

                if (unlikely(!nskb))
                        goto err;



then I proceeded anyway
make KERNELS="linux-2.6-xen" dist
and installed it with ./install.sh

I followed that with
cd /boot
mkinitramfs -o initrd.img-xen.3.1.0 2.6.18-xen
depmod  2.6.18-xen

Now on reboot the modules aren''t loading complaining about unknown
symbols, etc.
So I''ve done something (or somethings) wrong.

What is the correct proceedure?

Thanks.
Chris.

It has been discussed many times on this list that upgrading to another 
kernel, even if just a seemingly small step as in your case, is nothing 
an average user should try to do. It takes deep knowledge and 
understanding of kernel and xen code.

Even if you get it working you will propably be less stable than what it 
may look like in the first place. So bottom line is something like "if 
you do not really know what you are doing, don''t try it and
don''t expect
any support".
