  Not able to analyze the dump using crash tool

Status in crash package in Ubuntu:

Bug description:
  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.
