I would expect uname -r to say 2.6.18-164.el5. > I have the following questions: > 1.Did I install the correct rpm's? kernel-devel-2.6.18-164.el5.x86_64 is missing. > 2.Where can I find the correct kernel-devel? It should be on Red Hat Network (well, 2.6.18-164.0.0.0.1 probably isn't but 2.6.18-164.el5 probably is). > 3.Can it be omitted? Only if you compiled the stap modules on a system that has it.

It looks like kernel-debuginfo and kernel-devel for that version are missing. I am not sure where you got version 2.6.18-164.0.0.0.1 because it doesn't sound like something that was every built by Red Hat and if it was, I doubt it has ever been released. What does "rpm -qa | grep kernel" say? What version are you booting on (as per grub.conf).
