Chuck,

i cannot email you because the mail always bounces ...

the kprobes benchmark is a simple "NOP" function:

 static int counter = 0;

 static int probe_pre_handler (struct kprobe * kp,
                               struct pt_regs * regs)
 {
         counter++;
         return 0;
 }

i've attached it.

	Ingo
