Known bug, applies to all SCSI controllers. Fixed on the utf8-r0 CD. 
Fixing it by remastering your existing 6.1-2 CD with the proper 
initramfs is also easy.

The thing is that the buggy initramfs has /dev/sr* devices but looks at 
/dev/scd* for your CD. So you should be able to mount the CD, copy all 
files (including hidden ones) to some temporary directory, unpack 
/boot/isolinux/initramfs_data_cpio.gz, and edit the /init file. Replace 
/dev/scd* with /dev/sr*. Pack again with the following command:

find . | cpio -o -H newc | gzip -9 > ../initramfs_data_cpio.gz

Then remaster the CD:

mkisofs -R -l -L -D -o \
     ../lfslivecd-x86-6.1-2.iso -b boot/isolinux/isolinux.bin \
     -c boot/ -no-emul-boot -boot-load-size 4 -boot-info-table \
     -V "lfslivecd-x86-6.1-2" ./

Then burn the resulting image, it should work. Or just use the utf8-r0 
image if this is easier for you :)
