HI,

I'm trying to build centOS6.0 custom kernel using the steps given at URL http://wiki.centos.org/HowTos/Custom_Kernel Kernel: 2.6.32-71.el6.x86_64.

I'm following centOS5.0 steps for building custom kernel (This is the latest one to refer). After I get rpms in `/rpmbuild/RPMS' i installed the following RPMS to boot with the new custom kernel. su -c "rpm -ivh $HOME/rpmbuild/RPMS/x86_64/kernel-2.6.32-71.el6.kasivj.x86_64.rpm \  $HOME/rpmbuild/RPMS/x86_64/kernel-firmware-2.6.32-71.el6.kasivj.x86_64.rpm \  $HOME/rpmbuild/RPMS/x86_64/kernel-headers-2.6.32-71.el6.kasivj.x86_64.rpm \  $HOME/rpmbuild/RPMS/x86_64/kernel-devel-2.6.32-71.el6.kasivj.x86_64.rpm"

This will add a new kernel entry in /boot/grub/menu.lst along with oldone. (default 0) followed by new kenel. I checked for initramfs, vmlinuz, config, system-map files created for new kernel as shown below.

bash-4.1$ ls /boot/ ============= config-2.6.32-71.el6.kasivj.x86_64         symvers-2.6.32-71.el6.kasivj.x86_64.gz config-2.6.32-71.el6.x86_64                symvers-2.6.32-71.el6.x86_64.gz efi                                        System.map-2.6.32-71.el6.kasivj.x86_64 grub                                       System.map-2.6.32-71.el6.x86_64 initramfs-2.6.32-71.el6.kasivj.x86_64.img  vmlinuz-2.6.32-71.el6.kasivj.x86_64 initramfs-2.6.32-71.el6.x86_64.img         vmlinuz-2.6.32-71.el6.x86_64 initrd-2.6.32-71.el6.x86_64kdump.img

two questions:- 1. Grub menu centOS6-2.6.32-71.el6.kasivj is not displayed 2. If I remove old kernel and keep the new kenel, then new kernel is not booting.

I suspect that below step given in the URL I was not able to do it for centOS6.0.

[[[Starting at line 698, there is a 25 line block of code that needs to be commented out to build customised CentOS-5 kernels ( This step is not required to build customised CentOS-4 kernels): ]]]]]

Am I missing somethign here to build custom kernel centOS6.0

Reason for building: LKLM modules built on 2.6.32-71.el6.x86_64 i'm not able to load them. thanks and regards, Viswa
