Your kernel appears to include O(1) scheduler, but for some reason does not
export that set_user_nice() function to modules. Strange.

Quick fix is to add such export statement to your kernel source, and then
re-compile and install new kernel. You can add that export like this:

    cd /usr/src/linux-2.4.18
    echo 'EXPORT_SYMBOL(set_user_nice);' >>kernel/ksyms.c

Then build + install new kernel normally. Something like this:

    mv .config z
    make distclean
    mv z .config
    make oldconfig
    make dep && make clean && make bzlilo INSTALL_PATH=/boot
    make modules && make modules_install

Then compile new loop-AES module, like this:

    cd /usr/src/loop-AES-v3.1c
    make LINUX_SOURCE=/usr/src/linux-2.4.18

And finally boot your new kernel.

Bernhard,
Can you post a download link to your kernel source on your distro vendor
server, or some other place. I want to see this kernel source myself.
