Continuing previous mail I did a mistake in answer no. 7.
instead of 
"... I am able to get ...
it should be
 "........I am not able to get .... ".

Dear Sir,
Here are the answers of your question=>
1.My machine is DELL OPTIPLEX 990 MODEL which has INTEL i5 processor, 4GB RAM, 500 GB HDD with windows 7 original  installed.
2. I have installed ubuntu 12.04  on my system and  updated kernel from 3.2.0 to 3.8.5 by compiling from source code to include lock stat, oprofile support.
3. I have download oprofile from it's site and installed from there.
4. oprofile version---0.9.8
5. I am using operf as opcontrol is not properly  working --it is showing it is old , operf is recommended
6.I am able to get user space data correctly, it is annotating my source file.
7. when I am using opreport it is showing around 90% of samples belong to vmlinux but I am able to get details of vmlinux like in which functions of kernel it is taking time.
When I am trying to profile kernel using following command in Oprofile i am getting following error, 
 opreport --symbols /lib/modules/`uname -r`

error: no sample files found: profile specification too strict

If possible please try to help as much as possible.

Please be more specific.
 - What architecture/processor model are you running on?
 - What Linux distro are you on?
 - Are you using the distro-provided oprofile or are you building your own?
 - What version of oprofile?
 - If using oprofile 0.9.8, are you using operf or "legacy" opcontrol-based profiling?
 - Are you able to collect profile data for userspace programs OK?
 - Exactly what do you mean by "profiling the kernel is not working"?
