chris pollock, just to clarify Launchpad is not the correct venue for reporting issues with the upstream kernel.
However, Launchpad is the correct venue for your problem, as it is reproducible with the Ubuntu kernel, and as a part of the debugging process, the upstream kernel is tested. Despite this, for regression testing purposes, could you please test for this via http://releases.ubuntu.com/saucy/ and advise to the results? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1402331 Title: System will periodically lockup with [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1402331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
