Example display corruption

+++ This bug was initially created as a clone of <a class="bz_bug_link 
          bz_status_RESOLVED  bz_closed"
   title="RESOLVED FIXED - [NV4C] computer hangs after few minutes of use"
   href="show_bug.cgi?id=91992">Bug #91992</a> +++

Hardware is NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2) on an
old Dell Inspiron 531. Integrated graphics.

The system boots OK (with high-resolution console) into X11. I can log in to a
Lubuntu desktop (2D, no OpenGL, AFAIK). Then, from a terminal window I run:

$ while true; do nice -n19 glxinfo > /dev/null; done

Then I drag the window around for a few seconds. Then the entire system
crashes: total system lockup, followed by display corruption a second or two
later. (I've attached a photograph, because I can't take a normal screen shot.)
No Ctrl-Alt-F1, no magic SysRq, no ping response.

Other OpenGL apps (i.e. glxgears) can run...sometimes. Other times, they crash
the same way. It seems to happen on GL init.

Ubuntu 16.10 (with Lubuntu Desktop)
Linux kernel        4.10.0          (freshly compiled)
libdrm              2.4.70-1        (from distro)
Mesa                12.0.3-1ubuntu2 (from distro)
xf86-video-nouveau  1:1.0.12-2      (from distro)

This seems a lot like <a class="bz_bug_link

   href="show_bug.cgi?id=91992">bug 91992</a>, but I've got my video memory cranked up to 256
MB in the BIOS settings, and it still happens.</pre>
