A question ?
why are you downgradding a centos 6 kernel to a centos 5 kernel ?
el6 is cent 6 and el5 is cent5
also centos6 is using "dracut"
here is a handy script a created to rebuild the boot image
( i was testing a knod-nvidia rpm for the dev's and needed a quick way of NOT making a typo)
place it is /
"boot.image.rebiuld.sh"
Code:
#!/usr/bash
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r ).img.backup
dracut -f /boot/initramfs-$(uname -r).img $(uname -r)
