[Bug 1522212] [NEW] kernel panic involving threading

 

You have been subscribed to a public bug:

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.
