My comments -

1. Most of samples (CPU_CLK_UNHALTED.CORE) were dropped in vmlinux, that means target application is not very busy during sampling data collection. Linux* system modules provide service, e.g. IDLE handler.

2. Unresolved address, I know that usually was caused byCompressedLinux* kernel module used.

Hello Peter
Ya you are right its that, Vtune looks for vmlinux and my system has vmlinuz.
Can you help me resolve it.

"vmlinuz" means that you are using Linux compressed Linux* kernel.

VTune Performance Analyzer shows my Linux* modulelikeas "vmlinux-2.6.18-9.el5". So please work (boot from) on uncompressed Linux* system.

Thanks, Peter
