If you do a SIGINFO (normally control-T), it ought to give more specific
information about what it's doing.
Are you restoring to an empty new filesystem which has just been newfs'ed with
similar inode parameters to the original source of the backup?

I haven't seen that sort of problem myself. Are you sure the original
filesystem is OK and doesn't contain any weird symlinks which could have
confused dump? Try to fsck it and test a new dump/restore sequence.
Did you use the -L flag to dump using a snapshot, that may help...
