I've experienced same behavior. It always happened when sd(4) driver is in use and never with wd(4). I managed to enable FDE using random disklabel(8) tricks. This is probably a bug in sd(4). Try to initialize your disk with standard disklabel without CRYPTO first (e.g. via installation program then exit to shell). Then perform the steps from FDE guide. -- Ivan Markin
