[Bug 908387] [NEW] Module aesni_intel not being loaded before mounting LVM2 stacked on LUKS

[Launchpad Bug Tracker]

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.
