You appear to be having the same problem I just had.

If you followed the the chapter about compiling and then configuring
grub you will have a menu.lst file in boot/grub your entry for root
might look something like root=/dev/hda# if you are doing lfs 6.5 and
using kernel change your root entry to root=/dev/sd# and also
in your fstab file change all your hd entries to sd example /dev/hda1
and /dev/hda5 will be /dev/sda1 and /dev/sda5

That should fix your problem. It did for me.
