debdiff for trusty SRU ** Description changed:
+ [SRU justification] + This represent a hardware enablement SRU : Firmware assisted dumps (fadump) are not possible on LTS. + + [Impact] + The fadump mechanism cannot be used on Power systems running Trusty + + [Fix] + Backport fadump functionality from makedumpfile 1.5.8 present in Wily and onward. + + [Test Case] + See comment #9 : The proposed SRU has been tested from a PPA on a Power VM. + + [Regression] + None expected from a functionality point of view as it is a new feature. Existing code paths are minimally modified. + + [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) In order to use Firmware Assisted Dump feature update the kernel command with fadump=on. 4) Reboot.
