GELI + Soekris = Error

[Nick Evans]

Tried a GELI partition tonight on a system with a Soekris VPN1401
board. The Soekris works fine with OpenSSL, OpenSSH and the like, but
when trying to attach a newly init'd GELI partition I get the following
errors:

GEOM_ELI: Device ad0s1g.eli created.
GEOM_ELI:     Cipher: AES
GEOM_ELI: Key length: 128
GEOM_ELI:     Crypto: hardware
GEOM_ELI: Crypto READ request failed (error=1819180009).
ad0s1g.eli[READ(offset= 0, length=8192)]
GEOM_ELI: Crypto READ request failed (error=-1027453240).
ad0s1g.eli[READ(offset =4096, length=4096)]
GEOM_ELI: Crypto READ request failed (error=-1035087872).
ad0s1g.eli[READ(offset =0, length=4096)]

I've tried init with both the default 128-bit AES and 256-bit AES with
no change. /dev says the GELI device is there, but dd'ing it
immediately fails.

Anyone else tried this with success?
