Taking a wild guess, but looks like the filesystem is screwed, possibly (current process: swapper) the node that defines the start of the swap partition. To rule out any filesystem issues, try booting from cd-rom. If that works, mount ad1s1a from the rescue console (as /mnt for example). -- Mel _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
