First of all, doing ponytail on a 3 year old bug is not going to bring you much attention.

Especially since this bug pertains to a mechanism that is now only used on Precise. It is unfortunate though that the server guide is misleading on how to configure kernel dump. I would suggest to open a bug against the server guide to have this fixed.

This page does a pretty good job at documenting how to generate a kernel crash dump :

 https://wiki.ubuntu.com/Kernel/CrashdumpRecipe

TL;DR : Once the linux-crashdump package has been installed & the server rebooted you need to change the following in /etc/default/kdump-tools :

USE_KDUMP=1

Then :

 $ sudo kdump-config load

For any other visiting this bug, please refrain from adding to it, it is no longer relevant as the kernel dump mechanism has changed
