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.

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.
