BTW: Ubuntu ships by default with

	crashkernel=384M-2G:64M@16M,2G-:128M@16M

What is the complexity for the user? I didn't edit /boot/grub/menu.lst,
I just installed kexec-tools and a few other kdump-related packages, and
then this was in my menu.lst.

Don't make the kernel complex. Make the userspace complex.
