Thank you Cascardo for the reply,

We tested in couple of systems with 512GB RAM and we are able to use
your makedumpfile to dump the vmcore on  4.13.0-32-generic kernel on
Bionic.

Description: VMcore extraction tool
This program is used to extract a subset of the memory available either
via /dev/mem or /proc/vmcore (for crashdumps). It is used to get memory
images without extra unneeded information (zero pages, userspace programs,
etc).

Can you point this makedumpfile over web link which we can wget to
install it on 16.04.4 (reason we are asking this is, we will be doing
hardware certifications and kdump test will fail on 16.04.4)

We request for your comment on inclusion of this version makedumpfile on
16.04.4 after we test it.

  update makedumpfile tool version to v1.6.3

Status in The Ubuntu-power-systems project:
  In Progress
Status in makedumpfile package in Ubuntu:

Bug description:
  [Impact]
  New upstream kernel versions, as those in linux-hwe package, require a newer 
makedumpfile to be supported. Otherwise, all copies fallback to copying the 
entire memory.

  [Test case]
  kdump-tools has been installed, system rebooted, then crash trigerred and 
verified that a small dump file was present on /var/crash/. Tested on amd64 and 
ppc64le.

  [Regression potential]
  Many other bug fixes have been included in the latest version of the package. 
The changes are supposed to fix these bugs, and have been tested as well. 
However, as the total of changes is not trivial, there is impact of regression 
that has been minimized by the tests done. Regression potential of not 
supporting older kernels has been tested with the kernels shipped on xenial and

Naveed, what was the size of the vmcore saved through 'cp'? What is the total
RAM size on the system? please share the proc/device-tree info (sys.dts) on
the system it failed

$ dtc -I fs /proc/device-tree -O dts -o sys.dts

Thanks
Hari

  update makedumpfile tool version to v1.6.3

Status in The Ubuntu-power-systems project:
  In Progress
Status in makedumpfile package in Ubuntu:
  Fix Released

Bug description:
  [Impact]
  New upstream kernel versions, as those in linux-hwe package, require a newer 
makedumpfile to be supported. Otherwise, all copies fallback to copying the 
entire memory.

  [Test case]
  kdump-tools has been installed, system rebooted, then crash trigerred and 
verified that a small dump file was present on /var/crash/. Tested on amd64 and 
ppc64le.

  [Regression potential]
  Many other bug fixes have been included in the latest version of the package. 
The changes are supposed to fix these bugs, and have been tested as well. 
However, as the total of changes is not trivial, there is impact of regression 
that has been minimized by the tests done. Regression potential of not 
supporting older kernels has been tested with the kernels shipped on xenial and 
artful as well.

Hello Cascardo, we don't see the fix package in -proposed yet.
When could we expect it there..?
