We met this situation in meego too:
https://bugs.meego.com/show_bug.cgi?id=18156
There's quite a lot BUG_ON in the code path of sync or umount. If you unplug a
usb or sd card before umount or immediately after umount, you will hit problem
like this. I am now working on a patch to handle this

it as subvolume. So
the solution is to check if what we find is really a subvolume.

A similar bug has been reported by Kenneth Lakin [kennethla...@gmail.com] last
week. It's related to my check-in (git commit
914ee295af418e936ec20a08c1663eaabe4cd07a). I am looking into it now.
I found one suspicious code in prepage_pages (fs/btrfs/file.c):
start_pos = pos
I have checked latest mkfs code. If page size is 4k. sector size will be 4k
too. So at least for x86 hardware, page size and sector size will always be the
same.
