on comment #125 there is the /debug/dri/0/i915_error_state with 3.5.0-28 kernel, with this kernel compiz and unity crash immediately after the login and graphics quickly become corrupted, I didn't waited Xorg to be locked up as anyway it isn't possible to work with that kernel
with all these kernels I can kill Xorg and log into a console to grab /debug/dri/0/i915_error_state without need to do it with ssh from another pc -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1140716 Title: [regression] 3.5.0-26-generic and 3.2.0-39-generic GPU hangs on Sandybridge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1140716/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
