kern.log relating to nouveau driver and system lockup

Ok, over the last few months my system has gone from "rock solid, runs forever" to "it will crash at least once today, if not 3 or 4 times". Given I'm running Ubuntu 16.04 I've sort of been ignoring it hoping someone is making it better, but it keeps getting worse, and every time it crashes I have 3-4 hours of RAID sync to live with.

I'm running a NVIDIA Corporation GF108 [GeForce GT 430] (rev a1), one screen :: 2560x1440 @ 60Hz.

Symptoms, screen locks up, comes back after 1-2 mins just long enough to refresh the screen - then freezes.
