Comment 7 for bug 1502531

The janitor closed this a few days ago, but with holiday break rolling around I was finally able to test this on my HP Spectre x360 (please let me know if a new bug should be opened rather than continuing this one).

I downloaded the debs for mainline kernel v4.4-rc6-wily, and the problem is fixed upstream. I've attempted to modify the tags as requested. For now I'll continue running the mainline kernel, but I look forward to being able to shift back to the supported Ubuntu kernels.
