I've applied this to next/fixes-non-critical now. I'm fairly confident
that this helps more than it can hurt, but not confident enough
to put it into 3.17 or stable for now.

It would be nice to get some testing from someone with
hardware access. If necessary, I'll revert the change or
do a fixup on top.
