I start oprof_start as root and this dialog warns me:
--------------------------------------
/usr/bin/opcontrol return 1
Failed:
FATAL: Module oprofile not found
FATAL: Module oprofile not found
Kernel doesn't support oprofile

Command was:
/usr/bin/opcontrol --init
--------------------------------------

So do I need to activate something in the kernel and recompile? What
should I do?
