Encrypted device cannot be found during boot, mounting fails


Hey there i tryed to mount my dm_crypted device during boot, but it does not work.

This is my /var/log/bot with uncommented "set -x"(debug output) in " /lib/cryptsetup/cryptdisks.functions" and correct /etc/crypttab

This is my crypttab, everything gets unlocked expect from sdb1_crypt:

Code:
#<name>     <device>  <pass>       <options>
sdb1_crypt /dev/sdb1 none         luks,timeout=0
#Swap
sda2_crypt /dev/sda2 /dev/urandom cipher=aes-cbc-essiv:sha256,size=256,swap
#Root
sda3_crypt /dev/sda3 none         luks,timeout=0
This is my fstab, again everything works, expect sdb1(because it does not get unlocked, so "/dev/mapper/sdb1_crypt" cannot be found):

Code:
#System
proc                                                /proc           proc    defaults                          f    0       0
#Root
/dev/mapper/sda3_crypt                              /               ext3    errors=remount-ro 0     1
#Boot
/dev/sda1                                           /boot           ext3    defaults        0       2
#Swap
/dev/mapper/sda2_crypt                              none            swap    sw              0       0
#Data
/dev/mapper/sdb1_crypt                              /data0          ext3    defaults        0       2
The folloing steps happen on boot:
1. grub
2. initram
3. Debian asks for "/"-partition password
4. Debian SHOULD ask for sdb1-partition password
5. swap gets "mounted" with random passphrase
6. booting continues

What i did:

I ran update-"initramfs -u -k all -v"
I fixed my /etc/crypttab, a "#" was missing at the beginning
I can mount the device with cryptsetup / mount after boot.

I´m running debian 6.0.6
kernel 2.6.3.2-5-amd64 x86_64
Version of cryptsetup is 2:1.1.3-4squeeze2
