If you are running debug, there is a sysctl flag for write reordering
which occurs whether or not the thing is mounted async.  If you aren't
running debug, you should grep -i for sysctl in the sys/ufs/ufs/ufs*.c
sources and change the manifest constant to disable this behaviour.

I *think* this will fix it (temporarily, at least).
