dmcrypt works with AES-NI without problem.

If it is during boot, probably just some modules are missing in your initramfs.

I remember exactly the same problem and it was caused by missing crypto/fpu.ko
kernel module, adding module to initrams explicitly
like "dracut --force --add-drivers fpu" helped in this case (on Fedora).
