This doesn't seem to work either with my RH 8.0 system
(kernel-smp-2.4.18-24.8.0):

   # rpm -q oprofile
   oprofile-0.3-0.20020806
   # op_start --vmlinux=/boot/vmlinux-2.4.18-24.8.0smp --ctr0-event=CPU_CLK_UNHALTED --ctr0-count=600000
   Failed to open profile device: Bad address
   Couldn't start oprofiled.
   Check the log file "/var/lib/oprofile//oprofiled.log" and /var/log/messages

The file /var/lib/oprofile/oprofiled.log exists but is empty. The file
/var/log/messages contains: 
   
   Mar  7 11:22:54 bach kernel: oprofile: failed to allocate hash table
   of 8388608 bytes

Is the only solution to build my own kernel with the latest and greatest
oprofile?
