up to here, everything seems fine: mdadm is started but no software raid
configured, then lvm is started but no volume group available yet.

that one indicates that the root device is not available to cryptroot.
for some reason, the encrypted device (/dev/sda5) is not available.
either missing hardware driver or wrong device might be reasons.

in the initramfs emergency shell, please give output of the following
commands:

cat /conf/conf.d/cryproot

ls -al /dev/sda5

and if the device file exists, try unlocking it manually:

cryptsetup luksOpen /dev/sda5 sda5_crypt
lvm vgchange -a y
ls -al /dev/mapper/debian-root

if the device doesn't exist, then please give output of 'ls -al /dev'
from initramfs as well.

sorry, the command was wrong. please use the following instead:

sh -x mkinitramfs -o /tmp/initramfs 2.6.30-1-amd64 2>/tmp/initramfs.log

and attach /tmp/initramfs.log to the mail.

also, please update your initramfs, try to reboot with the broken
kernel afterwards and seee whether that helps:

mv /boot/initramfs-2.6.30-1-amd64 /boot/initramfs-2.6.30-1-amd64.orig
update-initramfs -c -k 2.6.30-1-amd64

sorry for asking that many questions, but i simply don't have a straight
idea what the problem on your system might be. apparently the same
kernel and system setup works for me.

greetings,
 jonas
