Can you still reproduce this issue with the latest version of QEMU
(currently v2.8)?

I haven't attempted to reproduce the issue recently, I'm afraid. I've
changed jobs twice in the intervening time, so the immediate issue for
me has gone away. If I find an opportunity, I shall try to reproduce
with the most recent versions.
