I guess that your custom 2.6.38 kernel misses the drivers to access your
root filesystem (maybe xfs drivers).

You mean "cryptpart set up successfully". That message indicates, that
cryptsetup luksOpen was successful.

You can ignore these messages. The cryptroot initramfs script tries to
start lvm and evms in case that the device is not available after

After waiting some time, you will be dropped into the initramfs
emergency shell. There, you should check the following:

1. was the encrypted root device really unlocked (i.e. does
   /dev/mapper/cryptpart exist).

2. is the UUID of the root fileystem you configured in /etc/fstab
   (f3231831-66c3-4f40-be43-ccde2144fba2) the same as for

   check this with 'blkid /dev/mapper/cryptpart, or by checking the
   symlink at /dev/disk/by-uuid/f3231831-66c3-4f40-be43-ccde2144fba2.

3. does the unlocked device at /dev/mapper/cryptpart contain your root

4. are you able to mount the root filesystem at /dev/mapper/cryptpart?
