---Problem Description---
A default offset of 128MB is enforced for crashkernel by kdump-tools utility
overriding the kernel default.

While the kernel default offset for crashkernel is also 128MB, that may change
and the right thing to do would be to let the kernel decide on the offset of
crashkernel in the default scenario.. 

Get rid of "@128M" in kdump-tools.cfg file

 
Contact Information = hbath...@in.ibm.com 
 
---uname output---
na
 
Machine Type = na 
 
---Debugger---
A debugger is not configured
 
---Steps to Reproduce---
 # cat /etc/default/grub.d/kdump-tools.cfg 
GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT 
crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M@128M"
---

The offset is specified via kdump-tools where as the kernel may be the right 
place to
set an offset by default..

 
Userspace tool common name: kdump-tools 
 
The userspace tool has the following bit modes: 64-bit 

Userspace rpm: kdump-tools
