I'm having the same problem in feisty. What I did and the error message:
> cryptsetup luksFormat /dev/sda2 WARNING! ======== Daten auf /dev/sda2 werden unwiderruflich überschrieben. Are you sure? (Type uppercase yes): YES Enter LUKS passphrase: Verify passphrase: Failed to setup dm-crypt key mapping. Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify that /dev/sda2 contains at least 133 sectors. Failed to write to key storage. Aufruf fehlgeschlagen. All modules are loaded, like aes, dm_crypt and dm_mod. The funny thing is that yesterday I had the same problem when trying to mount a crypt-formatted USB disk. Yesterday it didn't work, today it did! Now my USB disk is mounted, but I am not able to cryptsetup luksFormat an internal HD partition.... syslog says: Mar 31 16:01:02 hpsupercompi kernel: [ 8515.140000] device-mapper: table: 254:1: crypt: Device lookup failed Mar 31 16:01:02 hpsupercompi kernel: [ 8515.140000] device-mapper: ioctl: error adding target to table Mar 31 16:01:02 hpsupercompi kernel: [ 8515.144000] device-mapper: ioctl: device doesn't appear to be in the dev hash table. My version is the same as stated in the title, but without the "~edgy1" at the end. (it's in feisty, universe/admin) This seems to be the only show-stopper for using feisty as productive version..... (which is not recommended, I know, but I love some of the new features, that's why I'm trying...) -- fails to setup dm-crypt key mapping.
