Author: attilio Date: Fri Nov 13 22:57:20 2009 New Revision: 199260 URL: http://svn.freebsd.org/changeset/base/199260 Log: Add sysctls in ahd(4) in order to keep track of different classes of errors. So far 3 different classes are present (correctable, uncorrectable and fatal) but more can be added easilly.
