What happened, is you did an upgrade and the kernel got upgraded. The upgrade program (yum) is set to install the newer kernel package, and keep the latest/running kernel in case you have a kernel failure or something and have the older one to use. This is generally good practice and would recommend you to keep. -- Mike Chambers Madisonville, KY "Sex is like air, it's not important unless you aren't getting any!"
