           Summary: [NVE0] Display Freezes but SSH Works When Using OpenGL
                    Applications

Description:
When I am using opengl application, after a random amount of time of continuous
use my system will freeze. On the Diagnosing a Hang wiki page my machine
reaches level 3 where my display is frozen, but my mouse doesn't move nor does
my num lock key turn on my num lock light on my keyboard. My ssh connection
still works though. Attached is a log of me loading quake3-cpma (a mod to
ioquake3) and it immediately freezing on the main menu. Often times I can play
several matches before it freezes. I have also experienced this hang when using
mpv (a movie player).

Work Around:
Using the kernel parameter nouveau.noaccel=1 prevents lockups, but switches you
into using software rendering for opengl.
