Hi Tim,

Can we add the patch into new v3.13 maintenance patch? It affects many
people and we really needs this. Please suggest. Otherwise we have to
build custom kernel and we don't prefer custom kernel. Thanks.

btw, I checked out Ubuntu-3.13.0-87.133 which has the problem. And after
cherry-picking 9063e21fb026c4966fc93261c18322214f9835eb, the problem is
gone.

Perry
