Author: ae Date: Sun May 15 20:03:54 2011 New Revision: 221972 URL: http://svn.freebsd.org/changeset/base/221972 Log: Add a sysctl kern.geom.part.check_integrity for those who has corrupt partition tables and lost an ability to boot after r221788. Also unhide an error message from bootverbose, this would help to easier determine the problem.
