Running cryptsetup in initramfs with blackbox segmentation fault

3rdtreenz · 01-03-2009, 02:52 AM

I'm trying to boot with an encrypted root partition using an initramfs as described in:
http://en.gentoo-wiki.com/wiki/Initramfs#DM-Crypt .
In the initramfs, the "cryptsetup luksOpen /dev/sda1 crypt_volume" command gives a segmentation fault, yet once booted the cryptsetup program
works normally running the same command. How can I find the cause of this, are there any possible solutions?
The cryptsetup program is 1.5.0

Oops! problem was with dm-crypt being a module rather than in the kernel. Is it reasonable to copy the module into the initramfs and load it from there?
