Author: jkim Date: Thu Mar 10 22:20:11 2011 New Revision: 219467 URL: http://svn.freebsd.org/changeset/base/219467 Log: Detect NSC/AMD Geode SC1100 properly, not just Stepping 0. Although it is unclear that "TSC stops ticking with HLT instruction" problem is present with other steppings, it is limited to Stepping 0 for now.
