Kernel panic - not syncing: Attempted to kill init!

我用的是Red Hat Enterprise Linux 4,自带内核为2.6.9-22.EL
grub如下:
# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE:  You have a /boot partition.  This means that

#          all kernel and initrd paths are relative to /boot/, eg.

#          root (hd0,0)

#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00

#          initrd /initrd-version.img

#boot=/dev/sda

default=2
timeout=10

splashimage=(hd0,0)/grub/splash.xpm.gz

fdis -l的内容如下:
