You can provide us your dmesg debug output by adding the following lines
to /boot/loader.conf:

	kern.geom.eli.debug=3

	GELI(8) says:
   Debug level of the ELI GEOM class.  This can be set to a number
   between 0 and 3 inclusive.  If set to 0, minimal debug informa-
   tion is printed.  If set to 3, the maximum amount of debug infor-
   mation is printed.

For yourself you can add:

	kern.geom.eli.visible.passphrase=1

	GELI(8) says:
	If set to 1, the passphrase entered on boot (before the root file
   system is mounted) will be visible.  This possibility should be
   used with caution as the entered passphrase can be logged and
   exposed via dmesg(8).  This variable should be set in
   /boot/loader.conf.

Good luck.
