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-lts-vivid (hence upgrading kernel to 3.19) 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_RANDOMIZE_BASE=y kernel parameter to correctly 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://bugzilla.linux.ibm.com/show_bug.cgi?id=125712) 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.

SANT <ss...@in.ibm.com> - 2015-06-05 01:30:23 == (In reply to comment #1) > makedumpfile tool version, please? makedumpfile -v makedumpfile: version 1.5.5 (released on 18 Dec 2013) == Comment: #6 - SACHIN P. SANT <ss...@in.ibm.com> - 2015-06-24 06:25:13 == 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/v3.16/v3.19), we see this warning. 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 Hari To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1469054/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
