Paul Johnson, the next step would be to test to this issue on the latest mainline kernel via 3.19-rc2. If reproducible, one would want to gather the information requested by upstream in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1363313/comments/35 using that kernel. Then, you would want to personally report this via bugzilla as specifically requested by upstream following https://wiki.ubuntu.com/Bugs/Upstream/kernel . Please feel free to post the URL to this new report here once made so it may be tracked.
