Here are the configurations I have tested which all result in the errors
posted above:

  ("dm-crypt.ko" "aes-x86_64.ko" "crc32.ko" "pcbc.ko" "xcbc.ko" "sha256-ssse3.ko")
  ("dm-crypt.ko" "cryptd.ko" "aes-x86_64.ko" "crc32.ko" "pcbc.ko" "xcbc.ko" "sha256-ssse3.ko")
  ("dm-crypt.ko" "cryptd.ko" "crc32-pclmul.ko" "aes-x86_64.ko" "crc32.ko" "pcbc.ko" "xcbc.ko" "sha256-ssse3.ko")

I could also add "aesni-intel.ko" but it resulted in a different set of
kernel errors on boot:

  aesni_intel: Unknown symbol ablk_decrypt (err 0)
  aesni_intel: Unknown symbol lrw_free_table (err 0)
  aesni_intel: Unknown symbol ablk_set_key (err 0)
  ...
  ERROR: In procedure load-linux-module: Unknown error -1

For reference, here are all the modules loaded on my current system
which might be related:

  aes_x86_64 aesni_intel af_alg algif_skcipher arc4 ccm crc32_pclmul
  crc32c_intel crc_t10dif crct10dif_common crct10dif_pclmul cryptd ctr
  dm_crypt dm_mod gf128mul ghash_clmulni_intel lrw xor
