Xorg crashes after a while running glxgears. Debug messages from nouveau

previous crashes only changed Kernel.
This time i installed packages from xorg-edgers rebooted and ran glxgears.

After a while (opening browser, switch to virtual terminal and back)
system doesnt response and X is restarted

Attached log with debug messages from nouveau

--- Comment #4 from Pierre Moreau <pierre.morrow at free.fr> ---
There was some patches specifically for NVAA/AC cards that went into kernel
3.19. They solve a different issue, but it would still be worth to test it - a
lot of other patches were merged since 3.11, which might also help with it.
