Thank you for the reply.

I had tested on Ubuntu 12.04 and the Freescale Linux version (power arch--
P5020). Upon your response, I retested, and you are correct. It does work as 
expected on Ubuntu, so there must be an issue on the other version only. 

I will investigate some of the leads you suggested. I am a newbie with perf 
and perf development, so the suggestions help.

Thanks again.
