Hi Luc, in my previous comment (comment #15) I posted a link where I
uploaded the test kernel. Please download the 4 packages into your
disk. After that, you can install these packages from the command line
by running the command:
sudo dpkg -i *.deb
Thanks!

Hi Luis,
I can confirm that your kernel has fixed my problem. Adding a new
service to ipvs does no longer generate a kernel panic.
I had to install the following extra packages to compile your kernel:
crda
iw
wireless-regdb
Thanks for your fast response and solution.
Best,
Luc van
Hi, I'd like to test the latest kernel with the additional commit, but I
don't know how..
I've installed the 3.8.0-32.47 kernel from the raring-proposed source.
This kernel still panics (but you already know that), so I need to
install the addition commit. Can you tell me how to do this?

** Description changed:
In kernel 3.8.0-29 and higher (I've tested 3.8.0-30 and 3.8.0-31), the
kernel panics when adding IPVS service. Specifically, when I execute the
following command:
sudo ipvsadm -A -u 10.0.50.4:53
I confirm I'm able to reproduce this bug in Raring using the
instructions in the bug description. The problem is upstream commit:
dc7b3eb ipvs: Fix reuse connection if real server is dead
It causes a NULL pointer here:
1658 if (unlikely(sysctl_expire_nodest_conn(ipvs)) cp cp-dest

Kernel panic on 3.8.0-29 when using ipvs
I've uploaded a test kernel here:
http://people.canonical.com/~henrix/lp1238494/
Basically, this is a 3.8.0-32.47 (the Raring kernel currently in the
-proposed pocket) plus an additional commit:
0c12582 ipvs: add backup_only flag to avoid loops
This commit adds the initialisation of the ipvs
