Yea, interesting, the patch you sent out yesterday:
xfs: Don't use reserved blocks for data blocks with DAX
Makes this issue disappear in my system as well. Testing with v4.4-rc3
generic/083 fails 50% of the time or so in my setup, but with just that patch
added to v4.4-rc3 I can't make it fail.

I'm currently using xfsprogs v4.3.0, but the failure occurred when I was using
v4.2.0 as well.
