@Joseph Salisbury,

Hi.

It looks as if the Ubuntu kernel source has diverged from stable in a 
significant way.  In particular,
as has already been noted, on 3/10/2017, Canonical cherry-picked several 
patches from 4.11-pre, apparently relating to:

http://bugs.launchpad.net/bugs/1671613

Somewhere in there, I suspect, is the underlying cause of the present
BUG.

You already tried overlaying an essential fix-up,
d75450ff40df0199bf13dfb19f435519ff947138, as suggested in comment #52,
and that did appear to improve stability, but not completely resolve the
issue for myself and others.

Looking at mainline, I see a rather large number of memory memory
management-related patches from Kirill A. Shutemov and others that
follow ace71a19cec5eb430207c3269d8a2683f0574306 "mm: introduce
page_vma_mapped_walk()" from 2/24/2017.  It could be that adding one or
more of those patches would stabilize the backported series relating to
http://bugs.launchpad.net/bugs/1671613.

The reason for this note is to observe that the absence of the present
BUG in 4.10.x stable may well be due to the absence of the Canonical
backported patches, rather than due to some additive fix.

Reverting the http://bugs.launchpad.net/bugs/1671613 patch series might
be another path to isolating the source of the BUG.
