---Problem Description---
kexec is not working with kernel 3.16 or later.
The root cause is missing patch in the kexec-tools package provided with Ubuntu 14.04 and 14.10.
---uname output---
Linux qemu 3.16.0-10-generic #15-Ubuntu SMP Thu Aug 21 16:32:31 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux
Machine Type = P8
---Steps to Reproduce---
On a 14.10 guest or host, run :
$ sudo kexec -l /boot/vmlinux --initrd=/boot/initrd.img-3.16.0-10-generic
$ sudo kexec -e
The kexeced kernel will hang here :
[ 300.002862] Starting new kernel
I'm in purgatory
The root cause is the following kexec-tools's patch missing:
2ca220389d21 kexec/ppc64: move to device tree version 17
This patch is required to kexec kernel 3.16 and later.
Among this patch, the following upstream pactches should be added to the current package :
335bad77fb07 kexec/ppc64: disabling exception handling when building the purgato
90853885a859 ppc64/purgatory: Device tree values should be read/stored in Big En

In addition the following incoming patch should be applied : lists.infradead .org/pipermail/ kexec/2014- July/012247. html)

Another option to consider is to move to kexec-tools 2.0.7, and to apply the missing patches
Is it possible to get this patches also applied to the kexec-tools shipped with 14.04 ?
