Just quickly grabbed ffs_vnops.c v 1.107 - the panic I had has gone, and
now I hit the same on as Christoph:

    slh_first = 0x0}}

so v_mount = 0.

(For some reason, after these panics, the non-journaled partitions don't
need fscking, but then e.g. (ld0h is journaled):

jacob# mount /usr/obj
mount_ffs: /dev/ld0h on /usr/obj: Operation not permitted
jacob# fsck -f /dev/rld0h
** /dev/rld0h
** File system is journaled; replaying journal
** Last Mounted on /usr/obj
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
