Dear Christopher M. Penalver, if a normal user like me can be asked to perform a git bisection on a kernel, I suppose it is reasonable to ask you to have a look at the linked bugzilla kernel report, read inside it the SHA of the commit that has landed into the stable branch and that solved this problem and finally track it up to the equivalent commit in the mainline kernel.
