The issue is that the 4GB are laid out "funny" on a GTX 970 (but =
not other
models), and nouveau doesn't properly handle that.

You had this problem on a 4.6 kernel, as it was the first to provide the
secboot firmware loading functionality (assuming you had the firmware in
place). To get back to the previous behavior, remove the firmware, or boot =
with
nouveau.noaccel=3D1 nouveau.nofbaccel=3D1 which should avoid initializing t=
he
graphics accel engine. (And hopefully avoid secboot as well, but I'm not 10=
0%
sure.)
