Thanks in advance.=20 LOCK_PROFILING does not work on FreeBSD 8.0-CURRENT. I loaded FreeBSD= 8.0-Current on my system, and try to run LOCK PROFILING. I have adde= d the =93options LOCK_PROFILING=94 to the configure file and rebui= ld the kernel. Then I reboot the system, and run =93sysctl =96a|grep = lock=94 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! I have repeated the same operations on FreeBSD 7.1, =93sysctl =96a|gr= ep lock=94 shows =93LOCK PROFILING=94 works. So what happens to FreeB= SD 8.0-CURRENT? Thanks, wenji
