Status in kexec-tools package in Ubuntu:
  Fix Released

  == Comment: #0 - SACHIN P. SANT  - 2015-06-04 06:03:17 ==
  ---Steps to Reproduce---
  1) Using latest daily ISO install 14.04.02 as a Power VM guest. The LPAR has 
vTPM functionality enabled.
  2) Upgrade the kernel to 3.19 level (3.19.0-18-generic)
  3) Configure kdump. A fix is required to configure kdump. Refer to defect 
(https://bugzilla.linux.ibm.com/show_bug.cgi?id=125712)
