Thanks for putting my issues in context with the rest. However, I'm still confused, as the 4th line of the above bug report says: "Uname: Linux 3.8.2-030802-generic x86_64" I currently have the i915.i915_enable_rc6=0 set (see e.g. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1153587/comments/9) and I had the i915.semaphhores=0 before. How can I set both at the same time? I set it in the /etc/default/grub as GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.semaphores=0". Can I add a second GRUB_CMDLINE_LINUX_DEFAULT? I am also wondering if the Virtualbox kernel additions might be causing problems. And another thought is that there may also be a problem in apport-gtk, as it really keeps bombarding me with more and more gpu hung apports if I try to submit the first one. If I click on "Cancel" instead, it leaves me alone. Except that the system just gets unresponsive after a while without any crash report...
