Bug Description
[SRU justification]
Newer trusty kernels trigger a supportability message from makedumpfile. The upstream version used on the release do not support those kernels.
[Impact]
Warning message when running makedumpfile on kernels higher than 3.11
[Fix]
Cherry-pick upstream commits that provide newer kernel support.
[Test Case]
1) Using latest daily ISO install 14.04.02 as a Power VM guest.
2) Install linux-virtual-
3) Configure kdump.
4) Trigger a dump. Dump is captured successfully without the message
"The kernel version is not supported." being displayed
[Regression]
Aside from cosmetic modification in README, the only sensible modification
it to adapt to the CONFIG_
fetch memory element. This config is enabled in new kernels.
[Original description of the problem]
---Steps to Reproduce---
1) Using latest daily ISO install 14.04.02 as a Power VM guest.
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:/
4) Trigger a dump. Dump is captured successfully.
During collection of dump following warning is shown on the screen. It would be good to fix this warning.
Starting kdump-tools: * running makedumpfile -c -d 31 /proc/vmcore /var/crash/
The kernel version is not supported. <<================
The created dumpfile may be incomplete.

Externalizing comment :
Each makedumpfile version supports kernel versions ranging from OLDEST_VERSION
till LATEST_VERSION (defined as macros in makedumpfile.h).
For makedumpfile v1.5.5, the LATEST_VERSION version is defined as 3.11.3.
As the makedumpfile tool currently shipped with ubuntu is based on v1.5.5 and
as the kernel version is higher (v3.13/
We can deal with this in a couple of ways:
1. Suggest Canonical to spike the LATEST_VERSION macro to 3.19 reinforcing support for kernel version 3.19.
2. Suggest Canonical to use the latest makedumpfile version (1.5.8) that supports kernel version 3.19
Thanks
