Hi John,

I don't think you provided the list with enough information. How did you get to this point? What did you install etc.? For example I don't have a opcontrol file that I am aware of.

I don't have much experience with xenoprof either. Could you provide links or packages and a litlle more background into the problem?

Best Regards,

Any help with following mail will be great. I am using oprofile 0.9.2. Also, when i run"opreport -l" I get segmentation fault. Running "opreport"  works correctly. Any help will be great. I am using fedora core.
