Ok, after some further testing I'm going to go ahead and say in my experience, this bug appears patched.
My uses with the GPU lock, while similar in symptom, appear to be a secondary unrelated issue. Interestingly when doing a hard reset into gnome-shell, I experience the issues above. When booting into unity and then logging out and logging into gnome-shell, I experience no issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/899159 Title: [snb-gt2] GPU lockup render.IPEHR: 0x7b009004 [Needs mesa 7.11+git] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/899159/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
