This is for the timer.profile probe.  It is implemented one of two ways
- either with register_profile_notifier, or register_timer_hook.  This
is due to an API change in the kernel - only the latter exists on
kernels >= 2.6.10.

It may simply be that the proper files are not being included on your
system.  Can you please check whether register_profile_notifier or
register_timer_hook exists in your kernel?  One or the other should be
in "include/linux/profile.h".  It looks like you're on RHEL4 U3 beta, so
I'm guessing it will be the former, but it's worth a check.

Thanks,

Josh

Yes, I am running RHEL4 U3 kernel. And yes, they existed in the kernel

cat /proc/kallsyms | grep register_profile_notifier
c0000000000602ec t .register_profile_notifier
c000000000060350 t .unregister_profile_notifier

Could you look into your kernel version's sources to see whether
there is a profiling timer hook?

Execute the timers.stp manaully, I got the folowing error
