** Description changed: + [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-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. + 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 <[email protected]> - 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 <[email protected]> - 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
