I have a lpar installed with ubuntu 15.04.I enabled kdump and on reboot getting error message "Cannot open `/boot/vmlinuz`".
Steps to recreate:
1. Install ubuntu 15.04 (netboot)
2. sudo passwd root
3. apt-get update, apt-get install openssh-server, apt-get nfs-common
4. service ssh restart
5. apt-get install linux-crashdump:

Selected "Yes"
6. vi /etc/default/
7. update-grub
8. reboot

On ppc, it should be looking for a file "vmlinux", not "vmlinuz". The former is the filename on the ppc distributions, the latter on amd64.
Can you try editing the grub.cfg to see if that fixes it?
if so, it's possible that whichever package modified the grub.cfg here, cannot handle the ppc case and need to be patched

I think the issue is with /etc/default/kexec file and not grub.cfg.
-------
kexec:
# Defaults for kexec initscript
# sourced by /etc/init.d/kexec and /etc/init.
# Load a kexec kernel (true/false)
LOAD_KEXEC=true
# Kernel and initrd image
KERNEL_
INITRD=
# If empty, use current /proc/cmdline
APPEND=""
# Load the default kernel from grub config (true/false)
USE_GRUB_
-------
Here KERNEL_

Looks like the kexec package needs some tweaks for ppc. Thx.
