Thanks for you reply. Sorry If I was not very clear, I'll try
explain better now:
1) I've got the last-kernel-stable 2.6.10, configured it as
described in the README: (from my .config) and rebooted with it
CONFIG_MODULES=y
# CONFIG_BLK_DEV_LOOP is not set
CONFIG_KMOD=y
# CONFIG_BLK_DEV_LOOP is not set
2) I've got the mount/losetup aes-patched version by
bash$ apt-get install loop-aes-utils
3) I've downloaded the loop-aes and installed it:
bash$ wget -c "http://loop-aes.sourceforge.net/loop-AES/loop-AES-v3.0b.tar.bz2";
bash# tar xjvf loop-AES-v3.0b.tar.bz2; cd loop-AES-v3.0b; make clean;
make [as root user]
4) I've tested it
bash# make tests [as root user]
.. as so got that error (with some more lines now):
[...]

I don't know what can being happened. So, I've did all in this
order (as you asked).

I'm getting the loop-aes-utils from the testing version, as show:

Package: loop-aes-utils
Priority: optional
Section: admin
Installed-Size: 240
Maintainer: Max Vozeler <max@xxxxxxxxxxxxx>
Architecture: i386
Version: 2.12p-2
Depends: libblkid1, libc6 (>= 2.3.2.ds1-4), libuuid1, mount (>= 2.12p-1)

MD5sum: 5e245c84fb65f8aa1d4ec8157b137677
Description: Tools for mounting and manipulating filesystems
This package provides the mount(8), umount(8), swapon(8),
swapoff(8), and losetup(8) commands with support for loop-AES
loopback encryption.
.
Purpose of this package is to provide users of loop-AES with
extended mount support that is not available with the crypto
patch in the 'mount' package.
.
On installation, this package diverts files from the mount
package and installs versions with loop-AES support in their
places. The diversions get removed on removal of the package.
.
This package is based on loop-AES 3.0a, util-linux 2.12p-2.

Any ideas about what can being happenig? In time, does the key
scrubbing feature offers some overhead that slow down the
encription/decription time?
Thanks in advance,
