When I started using systemtap, I had tried to compile my kernel and use
systemtap (binary -- came with fedora) on it. But I was not very
successful (I used to get a number of symbol mismatch/function not found
..etc errors) and finally I started using systemtap with Fedora kernel.
So far, it has worked fine.
$ stap -V

Some questions on compiling custom kernels
1. Should I compile and replace my existing systemtap with a newer
version in order to use it for a custom-compiled kernel? (Is there any
relation between system tap binary and kernel on which it is used?)
2. How to compile modules with debuginfo?
Thanks,
Om.

Glad to hear.

Any given systemtap binary should work fine with a range of kernels.
The runtime side (kernel module source code) is more kernel-sensitive,
but we have some mechanisms in place to make them work on a range
also.

If the main kernel has debugging information, the modules will too,
since they are compiled the same way.
