I cannot seam to be able to upgrade the system any more.. Did you try booting with the old kernel before you did the restore? In any case, at the very least we need your kernel config file and a dmesg (preferably a verbose one). Much better would be a crash dump: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html If you're trying to get a crash dump, be sure you have the debugging options enabled in your kernel config file (DEBUG=-g, INVARIANTS, WITNESS, etc.).
