Subject: [4.0] cryptsetup fails

Hi,

I wanted to give the new kernel a try, but the cryptsetup fails with:
[    8.747114] localhost.localdomain systemd-cryptsetup[280]: Set cipher aes, mode xts-plain64, key size 256 bits for device /dev/disk/[...]
[    9.265258] localhost.localdomain kernel: device-mapper: table: 254:0: crypt: Error allocating crypto tfm
[    9.265265] localhost.localdomain kernel: device-mapper: ioctl: error adding target to table
[    9.280993] localhost.localdomain systemd-cryptsetup[280]: Failed to activate: Input/output error

the error seems to get produced in drivers/md/dm-crypt.c:

5ebaee6d2       (Milan Broz     2010-08-12 04:14:07 +0100       1619)   /* Allocate cipher */
fd2d231fa       (Mikulas Patocka        2012-07-27 15:08:05 +0100       1620)   ret = crypt_alloc_tfms(cc, cipher_api);
fd2d231fa       (Mikulas Patocka        2012-07-27 15:08:05 +0100       1621)   if (ret < 0) {
fd2d231fa       (Mikulas Patocka        2012-07-27 15:08:05 +0100       1622)           ti->error = "Error allocating crypto tfm";
fd2d231fa       (Mikulas Patocka        2012-07-27 15:08:05 +0100       1623)           goto bad;

$ grep AES /boot/config-4.0.0-rc1-23421-g023a600 
# CONFIG_SND_MAESTRO3 is not set
CONFIG_CRYPTO_AES=y
CONFIG_CRYPTO_AES_X86_64=m
CONFIG_CRYPTO_AES_NI_INTEL=m
CONFIG_CRYPTO_CAMELLIA_AESNI_AVX_X86_64=m
CONFIG_CRYPTO_CAMELLIA_AESNI_AVX2_X86_64=m

any ideas what did change here? what am i missing?

with kind regards
thomas
