The wiki has a troubleshooting page that covers SMI issues: <http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingDapperSMIIssues> This page is linked from the Troubleshooting page (so you don't have to know what the problem is to find the solution :) ) I'm not sure if current distributions of EMC2 have the correct options set in the included RTAI_SMI module.
