I try to use high resolution kernel profiling today on FreeBSD 4.6
release. I use config -p -p MYKERNEL and later kgmon -Br to start the
profiling.  However, the file generate by gprof contains many negative
numbers such as -0.00, -0.02 under the columns of self and descendents.
Why is the case? Does it mean we should not use high resolution profiling
at all?

Thanks for any enlightment.
