no match while resolving probe point kernel.mark

[beginner966 <nitin966 at gmail dot com>]

Hi all,

I had put some static markers in the kernel, but later after recompilation,
when I tried to run a script to probe them, following errors were generated:

Running rm -rf /tmp/stapVpx5cd


When I tried to use :
# cat Module.markers
Nothing was printed on the screen.

The kernel was compiled and installed. 
The uname -r is 2.6.26.5-rt9.
The linux-headers for the kernel are missing in /usr/scr/, so there is no
modpost.c file.

Suggest some help. Thanks.
