Title:
  Module aesni_intel not being loaded before mounting LVM2 stacked on
  LUKS

Status in “cryptsetup” package in Ubuntu:
  Confirmed

Bug description:
  Hi,
  I've made an installation of Ubuntu 11.10 on a system with AES-NI instructions only to find that the aesni_intel module is not being loaded before mounting the root file system, leaving the system with software encryption instead of using the hardware capabilities.

  The problem I think it's due to the modules not existing on the
  initramfs. Naturally, aes_x86_64 and cryptd modules aren't loaded too.

  Having the kernel compiled with options
  CONFIG_CRYPTO_AES=y
  CONFIG_CRYPTO_AES_X86_64=y
  CONFIG_CRYPTO_AES_NI_INTEL=y

  instead of

  CONFIG_CRYPTO_AES=y
  CONFIG_CRYPTO_AES_X86_64=m
  CONFIG_CRYPTO_AES_NI_INTEL=m

  as it appears on "config-3.0.0-14-generic" in the /boot directory
  should be OK too.

  I can manually load those modules after the system boots, but then
  it's not useful for my fully encrypted filesystem.
