Bjoern, I had this problem earlier this week while using FreeBSD-12.0-CURRENT-amd64-20180628-r335760-memstick.img on my ThinkPad P50. I had used `dd` to place the img file on a partition (e.g. /dev/sdb1) of the USB pen drive and it wouldn't boot properly. After I used `dd` to place the img on the entire device (e.g. /dev/sdb), I noticed that it had its own partition scheme with three partitions, and that booted just fine.
