Looks like init got corrupted.

What machine is that? if you have ultrasparc2 (not 2e or 2i) processor
then it's quite possible to be iommu bug which was fixed in -current and
the bug actually manifested on dump|restore operation. You can try
pax instead of dump. And you can try to boot into single-user and
compare init with original.
