This is probably because you've compiled scsi as a module not in the
kernel. Either recompile saying Y to scsi / ext3 rather than M or
make an initial ram disk (this is the 'RedHat way').

You make an initial RAM disc with

  mkinitrd /boot/initrd-2.4.17ctx-5 2.4.17ctx-5

Then adjust your grub.conf thus

Add this line here :-

          initrd /initrd-2.4.17ctx-5
