Mouting of encrypted partitions under SuSE 9.3 (losetup, cryptotab, twofish256, twofishSL92)

I have one encrypted partition that was created under SuSE 9.2. After a fresh install of 9.3 (not an update) the mounting of that partition during bootup failed. I could, however, still mount it manually later using another loopdevice. To fix this, I had to change the encryption algorithm in /etc/cryptotab from twofish256 to twofishSL92. More detailed information.
