Doesn't happen on my test rig running a 3.10-rc3 kernel using
default mkfs/mount parameters for a rt fs on x86-64. more
information about your system is needed.

I don't see that either, but that indicates you are probably using a
non-default realtime extent size configuration. That's something
xfs_info output will tell us.
