The expectation for pstore is that the system will go through a reset when it
crashes. Most systems do not preserve DDR contents across reset.

Linux is in a constant state of change :-)

See above about DDR contents.   But if you have a platform that does preserve
DDR contents until your "mechanism" can copy the pstore buffer, then post
a patch.
