Christopher, why is this supposed to be a "graphics driver issue" that
would need to be split up into isolated bugs per GPU and per system (so
that none shows the "big picture" and aggregate Bug Heat of likely Mode
Setting or similar hardware re-initialization troubles on resume) ?

With the references of the original report
https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-
drivers-331/+bug/1341270/comments/0 to possibly related bugs edited out,
individualized instances may be made appear as of Low importance and
remain Unassigned for long (to what end though?), but freeze-on-resume
means a serious total loss of all unsaved data, potential file system
corruption and severe risk recurrent from earlier LTS releases where the
circumstances triggering it and their "solution" (some kernels simply
unaffected) never seem to have been fully understood either.

Guidance as to what contributions may be provided for the purpose of
debugging is much appreciated.

Per Wahlström at https://bugs.launchpad.net/ubuntu/+source/pm-
utils/+bug/999638 #18 et seq. had already made every conceivable effort
more than 2 years ago but there still seems to be no indication who
picked up how from there.
