Attaching .debdiff to this comment for SRU sponsorship consideration
into Eoan.

** Patch added: "makedumpfile_1.6.5-1ubuntu3.1.debdiff"
   
https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1741860/+attachment/5279278/+files/makedumpfile_1.6.5-1ubuntu3.1.debdiff

** Description changed:

+ [Impact]
+ 
+  * The value chosen for ppc64el of 128MB aligns with that of the kernel
+ default. That may change some day, so it would be best to let the kernel
+ decide what value it should use. If the value does change and the kernel
+ is not allowed to choose a value, this may stop the kernel from booting
+ on a production system.
+ 
+ [Test Case]
+ 
+  Run `cat /etc/default/grub.d/kdump-tools.cfg`
+ 
+  * Expected result: there is no offset specified at the end of the line
+ (.e.g, @128M).
+ 
+  * Actual result: For Xenial, Bionic, Disco, and Eoan there are offsets
+ specified.
+ 
+ [Regression Potential]
+ 
+  * Right now, the offset described in the kdump-tools.cfg aligns with
+ that of what the kernel would select, so since they are the same we
+ would expect no change in operation.

  ---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.. 
+ crashkernel in the default scenario..
  
  Get rid of "@128M" in kdump-tools.cfg file

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