[Bug 701044] [NEW] Semi-frequent freezes in nouveau
Public bug reported:
Binary package hint: xserver-xorg-video-nouveau
One or more times a week my computer display freezes. I can still move
the mouse, but the screen doesn't update.
I think nouveau driver enters an infinite loop and consumes 100% CPU. I
think the X0rg.0.log confirms this, but I only installed debug symbols
today. This happens semi regularly, so I can provide more information if
needed:
