Author: kensmith Date: Wed Mar 10 19:55:27 2010 New Revision: 204973 URL: http://svn.freebsd.org/changeset/base/204973 Log: Back out r203073 due to issues recently discovered with machine check hardware on some AMD processors that causes problems with running FreeBSD as a guest on some virtual machine monitors. What is believed to be the correct fix has been committed but should receive more testing before it becomes part of a release.
