Following your advice, I tested it on our current kernel build. One of
the Ubuntu kernel developper tested it as well and here is what we get :

> makedumpfile -g vmcoreinfo-3.2.0-24-generic -x ../../build/build-generic/vmlinux
> The kernel version is not supported.
> The created dumpfile may be incomplete.
> generate_vmcoreinfo: Can't find the memory type.

I am rebuilding makedumpfile from the latest source (our version is
1.3.7 which is rather old) and will try to debug it further. I will let
you know what I find.

Kind regards,

...Louis
