I would start adding printfs to the ffs_mountroot(), inittodr() and
ffs_unmount() functions to show what arguments they receive, what
timestamp they read or write and what decicisons they make. Building
and running the new boot kernel and then the regular kernel then might
give a more concrete clue on what's going on.
