Created attachment 84086 [details] 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
forgot software versions: latest log was with: - Kernel 3.11-rc5 xorg-edgers: libdrm-nouveau2 2.4.46+git20130702.c6d73cfe-0ubuntu0sarvatt~raring libgl1-mesa-dri 9.2.0~git20130729+9.2.9b8ad643-0ubuntu0sarvatt~raring xserver-xorg-core 2:1.13.4~git20130508+server-1.13-branch.10c42f57-0ubuntu0ricotz~raring xserver-xorg-video-nouveau 1:1.0.9+git20130730.300c5a32-0ubuntu0sarvatt~raring
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.
