CentOS - Dec 2012 - centos 6.2_x86_64, get black screen with blinking cursor after select item from GRUM menu.

Hi, all:
    
     I'm using centos 6.2-x86_64, the built-in kernel version is
2.6.32-220.el6.x86_64.

     Now I compiled kernel of version of linux-2.6.32-220.23.1.el6.x86_64, which
get from kernel-2.6.32-220.23.1.el6.src.rpm.

     I have put vmlinuz and initramfs into /boot directory, as follow:
     
[kdev at panda boot]$ ll /boot/vmlinuz-2.6.32-*  ./initramfs-2.6.32-*
-rwxr-xr-x. 1 root root  3938288 12?  7 2011 /boot/vmlinuz-2.6.32-220.el6.x86_64
-rw-r--r--. 1 root root  3952816 12?  8 19:23 /boot/vmlinuz-2.6.32-kdev-v1
-rw-r--r--. 1 root root 15888573  5? 26 2012
./initramfs-2.6.32-220.el6.x86_64.img
-rw-r--r--. 1 root root 15824301 12?  8 20:17 ./initramfs-2.6.32-kdev-v1

     and modified grub.conf like this:
#boot=/dev/sdb
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS62 (2.6.32-220.el6.x86_64)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-220.el6.x86_64 ro
root=UUID=f09cc6eb-99fa-4c90-a1a5-ad15277e8331 rd_NO_LUKS rd_NO_LVM
LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto 
KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM
        initrd /initramfs-2.6.32-220.el6.x86_64.img

title CentOS62 (2.6.32-kdev-v1)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-kdev-v1 ro
root=UUID=f09cc6eb-99fa-4c90-a1a5-ad15277e8331 rd_NO_LUKS rd_NO_LVM
LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto 
KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM
        initrd /initramfs-2.6.32-kdev-v1.img


   what i do is just copy the original section which beginning with title, and
then modified it with different version_string.
   But at last, after selecting the kdev-v1 item from grub's menu, i got a
black screen with a cursor blinking in the top-left, and paused there.

   If i select the original kernel,  namely 2.6.32-220.el6.x86_64, all thing is
correct. Is the GRUB gets wrong??
   My machine is : 
        motherboard: MSI  G41M-P26 
        cpu: Intel Celeron(R) CPU  E3400 

   Thanks ~~!!
