Try version loop-AES-v1.7b

A mkfs on 54 GB partition is going to take a while. How long did you wait
until you gave up?

You need kernel .config that matches your running kernel exactly (like
Jan-Benedict Glaw said earlier). And kernel source tree must be in fully
compiled form, as in after:

    make distclean
    cp /someplace/yourconfig-2.4.18.config .config
    make oldconfig
    make dep && make clean && make bzImage && make modules

And then compile loop-AES like this:

    cd ../loop-AES-v1.7b
    make LINUX_SOURCE=/path/to/your/kernel/source

Just running "make oldconfig && make dep" is NOT enough. I have tried that.
Got burned. Trust me on this one.
