It seems that you tried to patch the CentOS kernel and it didn't work. A patch for a newer kernel probably wouldn't apply clean, and the CentOS kernels coming from RHEL are heavily patched already. The last time I played in the kernel there were at least a hundred patches. Probably more. Any one of those could contribute to your new patch failing. I usually wouldn't recommend using a non-standard kernel on CentOS. If the kernel in the main repo or the plus repo doesn't suit your system, and you add a kernel from the main kernel.org sources, you risk de-stabilizing your system. An Enterprise linux like CentOS is designed for stability and long life and the pieces are fairly intertwined. If you need a custom patch or a newer kernel, I would just use a distribution like Gentoo or Slackware that seems to use newer parts, or see if someone already adds your patch to their current kernel.If you need a newer kernel to use that patch, I would recommend something that runs more cutting edge for that server, maybe Gentoo or Fedora 9. I don't recommend patching CentOS with a new kernel as you lose the main benefit for using an Enterprise distro .. stability.You meant I should not patch the newest kernel but original kernel, right? For example, I should download the source codes of kernel -2.6.18 used in CentOS 5 from www.centos.org and do patching. right? I am thinking the same method to achieve the highest stability. If you also recommend the way, I am willing to try again. Thanks! Ian
