I can confirm that this kernel fixes the problem for me as well,
including with the new keepalived build from precise-proposed which
fixes this bug

Title:
  Kernel panic on 3.8.0-29 when using ipvs

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  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

  The kernel immediately panics. I've reverted the kernel to 3.8.0-27,
  and IPVS executes without a problem.

  The panic is completely reproducable, using a clean install, no extra
  packages installed, all packages upgraded.

  I've attached the apport report of the system running 3.8.0-29.

  Best,
  Luc van Donkersgoed
