In the mainline kernel (not really mainline, because it is an extended version maintained by Canonical), the problem occurs between 3.13.11.5 and 3.13.11.6. I checked the git logs, but I am not expert enough to understand which commit may be the cause of the problem. I'll try to git bisect when I have some time.
