Why are you forcing a fast boot? Subsequent problems are the result
of not making your file system clean.

I don't know if there's a separate problem with init(8) dumping
core or the immediate consequence of the above.

boot -s and see what happens. If init(8) dies again, use a
different init(8) by setting init_path at the loader prompt.
SOmething like the following could do the trick:

	set init_path="/sbin/init.bak"
