I have added the “options    LOCK_PROFILING” to the configure file and rebuild the kernel. Then I reboot the system, and run “sysctl –a|grep lock” to check if the lock debugging has been enabled. But NO lock debugging related parameters show up. LOCK_PROFILING does not work on FreeBSD 8.0-CURRENT!

It certainly does work in 8.0.  Is it possible you forgot to install the 
rebuilt kernel?
