hi
when I try :
 
opcontrol --start
 
It doesn't work and the output is:
 
"Using 2.6+ OProfile kernel interface
Failed to open device. Possibly you have passed incorrect
parameters. Check /var/log/messages.Couldn't start oprofiled.
Check the log file "/var/lib/oprofile/oprofiled.log" and kernel syslog"
 
what should I do to make it work?
