So it appears that you can recreate this much more quickly than DaveJ
can recreate his issue.

The two issues may be entirely unrelated, but the it is certainly
quite possible that they have some relation to each other, and the
timing is intriguing, in that 3.17 seems to be the first kernel
release this happened in.

So at this point I think I'd ask you to just go back to your bisection
that you apparently already started earlier. I take it 3.16 worked
fine, and that's what you used as the good base for your bisect?

Even if it's something else than what DaveJ sees (or perhaps
*particularly* if it's something else), bisecting when it started
would be very worthwhile.

There's 13k+ commits in between 3.16 and 3.17, so a full bisect should
be around 15 test-points. But judging by the timing of your emails,
you can generally reproduce this relatively quickly..
