Please submit your question to either current@ (if using 8-CURRENT) or stable@ (if using 6.4-RELEASE or 7.0-RELEASE ~ 7.1-RELENG). They'll need to know what OS platform version it is (6.4, 7.1-RC1, etc), base platform architecture (i386, amd64), hardware configuration, and a few other relevant items. Cheers, -Garrett
