I did not have this problem on a 4.6 kernel, now the > kernel has been upgraded twice, 4.8.5, and now 4.8.6. No problems using a > 960 GTX w/4GB DDR5 memory, plus I have a secondary 730 GTw/1GB RAM. 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=1 nouveau.nofbaccel=1 which should avoid initializing the graphics accel engine. (And hopefully avoid secboot as well, but I'm not 100% sure.) -- You are receiving this mail because: You are the assignee for the bug.
