Is it possible that this may fix the "bad pte" panic with "TPTE at 0xffff8000040028c8 IS ZERO @ VA 800519000" that I saw at http://docs.FreeBSD.org/cgi/mid.cgi?1148482556.35287.18.camel ? I've only ever seen that panic once, so I can't really test this commit to see if it does indeed fix that issue. Thanks, Gavin
