loglevel of prink()

["J.H.Kim" <frog1120@xxxxxxxxx>]

Hi, everyone

When I added "loglevel=10" to grub menu option, only priintk() messages of level 4,5 and 6 were displayed.
This is  a part of "/boot/grub/menu.lst" that I modified :

title        Debian GNU/Linux, kernel 2.6.18-custom
root        (hd0,2)
kernel      /boot/vmlinuz-2.6.18-custom root=/dev/sda3 ro loglevel=10
initrd        /boot/initrd.img-2.6.18-custom
savedefault

How I should set boot parameter for all kernel messages in printk() to be displayed?
What's wrong with my grub memu?

Thanks in advance.
