  | (gdb) print vp->v_mount->mnt_flag
  | $4 = 4128
  | (gdb)

4128 is 0x1020 ... that is MNT_LOCAL (not surprising) | MNT_UNION (weird).

There were no union mounts in the fstab that you sent, is anything else
making one?   Can you show the output from "mount" while the system is
running (in as close to the state it would be just before a shutdown that
crashes as you can make it).

(Even if gdb were printing mnt_flag in hex (unlikely) the 0x20 bit
is set and that's MNT_UNION.)
