Since I was going back and forth between nouveau and the proprietary
nvidia driver for testing this bug, I ended up creating this bug report
while the proprietary nvidia driver was loaded. I don't know if that
messes up the information that you would want to collect.

Title:
  kernel panic involving threading

Status in xserver-xorg-video-nouveau package in Ubuntu:
  New

Bug description:
  my system:
  intel core i5
  nvidia 310m
  lubuntu 15.10
  sfml libsfml-dev 2.3.2+dfsg-1
  g++ 4:5.2.1-3ubuntu1

  I'm running my own cross-platform multimedia application.
  The program works as expected on this same ubuntu system with the proprietary nvidia driver and works as expected in Windows.
  This is how I conclude that the bug is in nouveau.

  This program uses sfml and c++ std::thread
  I send a thread to load some textures (into video memory), main thread shows a simple loading screen.
  artifacts on screen, then kernel panic

  I can reproduce the crash 100% on this system. I don't have another system to test it with.
  I have been unable to reproduce the problem with a smaller amount of code, I can zip up the whole project for you if you want.

  The problem does not occur if I just call the same functions in the
  main thread, only when I create a separate thread to load the
  textures.
