Como faço para atualizar meu kernel no CentOS 6 para a versão mais recente?

Question

Está me dando problemas e não está usando o mais recente, mesmo após o ciclo de energia.

[root@server ~]# uname -r

[root@server ~]# cat /boot/grub.conf

Eu listei todos os kernels e deletei todos os antigos.

[root@server ~]# rpm -q kernel
