Sounds like you created the LFS partition with a host e2fsprogs that uses 
custom features. Check in section 2.3 of the book for more information about 
this. Try booting with the host system and running "debugfs -R 
feature /dev/[lfspartition]" to check. If it does report custom features, 
then all you can do is restart the build from the beginning, recreating the 
partition with the stock e2fsprogs.
