Package: loop-aes-modules-2.6.26-2-686
Version: 2.6.26+3.2c-6+lenny1
Severity: grave
Justification: renders package unusable


# aptitude install loop-aes-modules-2.6.26-2-686
# modprobe loop-aes
# lsmod | grep loop
loop                   55372  0

Additionally, the nomenclature for loop-aes is not sexy. (The others
carry an underscore)
/lib/modules/2.6.26-2-686/extra/loop-aes/loop_blowfish.ko
/lib/modules/2.6.26-2-686/extra/loop-aes/loop_serpent.ko
/lib/modules/2.6.26-2-686/extra/loop-aes/loop_twofish.ko
/lib/modules/2.6.26-2-686/extra/loop-aes/loop-aes.ko

I've tried the same thing with etchnhalf BTW, without success.

In case someone is wondering about cryptoloop:

# modprobe cryptoloop
FATAL: Error inserting cryptoloop
(/lib/modules/2.6.26-2-686/kernel/drivers/block/cryptoloop.ko): Unknown
symbol in module, or unknown parameter (see dmesg)
# dmesg | tail -2
[ 5144.988320] cryptoloop: disagrees about version of symbol
loop_register_transfer
[ 5144.988326] cryptoloop: Unknown symbol loop_register_transfer

Please tell me I'm doing sth wrong and this is not all broken.
