What kind of distributions you've tested? In my case(ubuntu 11.04), it works correctly.
I suspect your machine's PMU status, wrong installation, or missing perf kernel module.

Hi, Apologies if the answer to this is someplace I have not looked. I've searched this list and other sites/FAQ's. I've noticed that command listed in the subject line always yields <not counted> cycles unless the target process is suspended. I have noticed this with a few different distributions. Is the fact that the target process has to be suspended at least once a known design limitation or would it be considered a bug? Thank you for your help.
