cryptsetup LUKS partition damages superblock

Hi folks!

/dev/sda6 is my LUKS encrypted root partition including arch 2009.08 based on 2.6.30-ARCH. I had a ntfs partition in /dev/sda1. After deleting partition /dev/sda1 I set up two new primary partitions called /dev/sda1 and /dev/sda3. Because I wanted to move /usr into /dev/sda1, I encrypted sda1 with LUKS and mounted the partition on /usr. The filesystem check during startup fails at /dev/mapper/usr due to a superblock error. It was not possible to use e2fsck on /dev/sda1 nor on /dev/mapper/usr.
