Great! I'm 2.6.18-92.1.18.el5.centos.plus! I don't se 2.6.20 in yum updates... is there any unstable repository I should enable?
You're playing with fire now. Newer kernels are not necessarily backwards compatible, and major breaks can occur. You are free to do as you choose, of course, but this is CentOS - you break it, you own it.
to clarify what MHR is saying for the benefit of the uninitiated... a given upstream EL major version (3, 4, 5) is released with a specific kernel, for instance, EL 5 uses 2.6.18. rather than releasing completely new kernels, upstream backpatches critical fixes into their 2.6.18 version, effectively creating a branch, the current version of which is 2.6.18-92.1.18.el5 (unless its been updated again since I last checked). This maintains near-total compatibility, so that a given release remains a stable platform for its entire lifespan.
