B.2 Enterprise Linux 3 (EL3)

For EL3, once again, Red Hat provides packages for oprofile that should be used rather than those downloaded from the oprofile Web site. The uniprocessor kernel does not provide the necessary oprofile drivers. Red Hat packages the necessary oprofile kernel modules with the smp or hugemem versions of the kernel. If you want to run oprofile, you must use the smp or hugemem kernel, even if you are running it on a single-processor machine.

More details on using oprofile in EL3 are provided at http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/sysadmin-guide/ch-oprofile.html.
