我在redhat9,原来的核是2.4.20上编译一个2.4.18的核,
我执行mkinitrd initrd-2.4.18.img 2.4.18,错误如下:
Nomodule BusLogic found for kernel 2.4.18
我的grub.conf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/sda2
#          initrd /initrd-version.img
#boot=/dev/sda

        root (hd0,0)
        kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
        initrd /initrd-2.4.20-8.img

        root (hd0,0)

重新启动后,错误如下
