I'm trying to install FreeBSD-10.0-RELEASE-amd64-memstick.img (dd'd to a memory stick).
I can boot from the memory stick but it gets stuck at mountroot, with error 19.

I have verified the checksum of the downloaded image, and it's fine.

What other information can I provide so as to enable some kind soul to identify the problem?
