--- Comment #1 from sigsys at gmail.com ---
This does seem to have been caused by r359612.  It apparently fixed a bug in
sys/ufs/ffs/ffs_inode.c (the MNT_SUJ flag being ignored), but it must also have
exposed other bugs.

By forcing the old behavior, there are no more panics during my tests.  There's
still something wrong going on there but way too complicated for me to figure
out.
