I've been seeing this as well. It's new with 3.2, and I haven't yet
been able to track it down.
The first thing that happens when we mount the FS is a block layer
invalidate, and that must be dropping the write.
It's also possible (but very unlikely) that mkfs.btrfs is neglecting to
write that block.
Do you have a reliable way to reproduce? If so, can you try with a much
older mkfs.btrfs.
