My coworker and I who are running the same model of machine are experiencing random lock ups. The holy hint is a message in the syslog and kern about the GPU hanging. I've included some data in the attached file.
It started recently for me within the last two weeks, definitely after some round of updates. Which ones I'm not certain of. ** Attachment added: "Commands with data" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/727594/+attachment/2582164/+files/data.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/727594 Title: SRU: [i915gm] GPU lockup (ESR: 0x00000001 IPEHR: 0x02000004) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/727594/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
