    I think it's simple.
    login as root , type up2date -uf kernel and then reboot your machine.

    Alternatively if u r running centOS then follow the steps below

    log into root

    yum update \kernel*

    check after install

    cat /boot/grub/grub.conf

    and then reboot the server


    BTW : seems that newest kernel version using the method above is CentOS (2.6.9-55.0.6.EL)

    Also for another step of precaution prior to rebooting:

    edit
    /boot/grub/grub.conf

    your new kernel should be on top of the list which is default "0". After you verify this, set the default field to your old kernel and save the change.

    Next type:
    grub

    then type
    savedefault --default=0 --once

    exit or quit

    If your box doesn't come back online with the new kernel, then get the DC to reboot which will then boot into your old working kernel. Once you verify things are all fine with the new kernel, then change your grub.conf default to 0.
