Sorry Chris, "Fix CommittedFixed, but not available until next release." made it sound like the upstream commit had been made and would fix the issue once 3.18 was merged in 15.04.
With regards to the bisect I can say with certainty it is one of these: https://lkml.org/lkml/2014/10/6/515 Is there any merit to me narrowing down a more specific commit? Would a patch be backported, or should I just wait for 15.04? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1382909 Title: Dell XPS 15Z Requires Kernel Parameters to Boot Correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1382909/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
