Karmic does not complete boot process

[Ralph Green]

I am testing koala and most days I update by running the following 2 commands.
sudo aptitude update
sudo aptitude safe-upgrade

 My system is a Compaq iPaq with a 933 MHz P3 and 512 meg of ram and 80 gig of hard disk. I used the Alpha 4 alternate installer to install. My swap partition is encrypted with a random password. My /boot partition is ext2 and unencrypted. My / and /usr partitions are logical volumes on an encrypted volume group.

 After the update on Aug 26, the system hangs on boot. The last line on the screen says:
modprobe: FATAL: Error inserting padlock_sha (/lib/modules/2.6.31-7-generic/kernel/drivers/crypto/padlock-sha.ko): No such device

The file /lib/modules/2.6.31-7-generic/kernel/drivers/crypto/padlock-sha.ko exists and is the same size as the one from the 2.6.31-6 kernel which still boots fine.
