            Bug ID: 99968
           Summary: [NV4C] System crashes reliably with glxinfo
           Product: Mesa
           Version: 12.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

Example display corruption

+++ This bug was initially created as a clone of Bug #91992 +++

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 bug 91992, but I've got my video memory cranked up to 256
MB in the BIOS settings, and it still happens.

Same, or similar, problem on Linux Mint 19.1 Cinnamon, with the same graphics
chipset.  The method I was using to reliably recreate the crash was to run
glxdemo and then resize the window.

However, the symptoms did occur at other times.  I turned off hardware
acceleration in chrome in an attempt to prevent it.  

Using "nouveau.config=NvMSI=0" as suggested here
https://bugs.freedesktop.org/show_bug.cgi?id=61321 made no difference.

Tried again on the same hardware with Linux 5.0-rc8, and it's not any better.
But now on top of that I've got intermittent system pauses, probably associated
with "rcu_sched detected stalls on CPUs/tasks" that I see in dmesg. That's
probably unrelated to the problem at hand.

Resizing the glxdemo window repeatedly does it for me, too.

nouveau.config=NvMSI=0 didn't help me, either.

A twist: I normally run this machine with modprobe.blacklist=nouveau, but it
still happened (while running Linux 4.15.0-20 from Ubuntu)...except this time
the system hadn't crashed, and CTRL-ALT-F1 (to get to tty1) followed by
CTRL-ALT-F7 (to get back to X11) restored video.
