Bug#568008: linux-image-2.6.32-trunk-amd64: Error inserting padlock_sha: No such device

[Julian Gilbey <jdg@debian.org>]

Package: linux-image-2.6.32-trunk-amd64
Version: 2.6.32-5

Every time I boot - and I'm using crypto file systems - I get the
series of messages (copied from bootlog):

Starting early crypto disks...sda2_crypt (starting)...
Unlocking the disk /dev/sda2 (sda2_crypt)
Enter passphrase: 
modprobe: FATAL: Error inserting padlock_sha (/lib/modules/2.6.32-trunk-amd64/kernel/drivers/crypto/padlock-sha.ko): No such device
Key slot 0 unlocked.

Any ideas what this FATAL error is about and whether it is a problem?
