I believe this is fixed by
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=61679fe153b2b9ea5b5e2ab93305419e85e99a9d
Try a more recent kernel? Or did you perhaps mean that you were
running into this with v3.15-rc4, in which case that commit didn't fix
the issue hard enough...
