Not able to analyze the dump using crash tool

[bugproxy]

Problem Description
=====================================
Not able to analyze the dump using crash tool

 ---uname output---
Linux ubuntu 3.18.0-8-generic #9-Ubuntu SMP Mon Jan 5 22:52:15 UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

Machine Type = P8

 Steps to Reproduce
======================
Install Ubuntu 15.04 on Power VM LPAR on P8 hardware.
Then loaded the kdump-config and triggered a crash in-order to verify the functionality of kexec and kdump tools.

After the crash has happened we got the dump files in /var/crash directory.
When we try to analyze the crash dump using the crash utility we get the below errors.
