Hrmph. Well it looks like your GPU just goes nuts.
[ 9.933619] nouveau 0000:01:00.0: bus: MMIO write of 00000002 FAULT at
13b154 [ IBUS ]

followed by a ton more 610xxx errors. 610xxx is PDISPLAY stuff, but 13b154 is
in PXBAR.GPC_*. I also can't find any way that we'd be writing to that
register, at least nothing too direct. Something we do greatly upsets the chip
though.
I looked through the nouveau changes between 4.5 and 4.6, and while there was a
ton of stuff, nothing jumps out at me.
Can you do a git bisect on the kernel between v4.5 and v4.6 (you can restrict
it to drivers/gpu/drm/nouveau) to figure out which change killed it?
Separately, you could see if it magically got fixed in v4.7 or v4.8-rcN.
