OK, but you've still not shown that you didn't accidentally make a mistake somewhere along the way. I asked you to confirm the exact steps you took because something doesn't make sense, so it's important to show what you actually did rather than retyping from memory what you think you did, in case you had made a mistake without noticing it. Here is the output of a FreeBSD 8.0 system showing that LOCK_PROFILING does in fact work as expected: gohan10# uname -a FreeBSD gohan10.freebsd.org 8.0-CURRENT FreeBSD 8.0-CURRENT #8: Sun Mar 29 12:06:13 UTC 2009 gohan10# grep LOCK_PROFILING root@gohan10.freebsd.org:/usr/src/sys/amd64/compile/CLUSTER amd64 /usr/src/sys/amd64/conf/CLUSTER options LOCK_PROFILING gohan10# sysctl -a | grep debug.lock debug.lock.prof.enable: 0 debug.lock.prof.reset: 0 debug.lock.prof.stats: debug.lock.prof.rejected: 0 debug.lock.prof.skipcount: 0 debug.lock.prof.skipspin: 0 Kris
