[Launchpad Bug Tracker <1415562@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

Starting from POWER6, the firmware now has a capability to preserve the
partition memory dump during system crash and boot into a fresh copy of
the kernel with fully-reset system. This feature adds the necessary
support to exploit the dump capture capability provided by Power
firmware.  With this feature support, the production kernel will
register for firmware-assisted dump using RTAS (Runtime Abstraction
Service) calls and builds required ELF header which then gets exported
through '/proc/vmcore' in the second kernel after crash.  This feature
improves Power serviceability by making it more robust compared to
current kdump mechanism on Linux.

Ubuntu 15.04 kernel already includes the necessary code for fadump. The
only kernel change needed is to enable CONFIG_FA_DUMP in the kernel
configuration. In addition, an update is needed for a script in kdump-
tools package.
