It seems that could possibly be unrelated at this point, but https://bugzilla.kernel.org/show_bug.cgi?id=16006 seems to have an answer. It is my error, but reading some of the comments here makes me think this bug report might not be the same as 515937, but could be causing some of the issues reported here. Hopefully we can get the ball rolling on a kernel update soon. :)
