I have exactly the same problem with recent -current sources with my
ThinkPad X31. I had to tell the loader to boot /boot/loader.old
and then i copied loader.old to loader and since then i have no
problems, but i do this after each rebuild. So, it's clearly something
wrong with the loader, but i wansn't able to find something suspicious
looking at recent commit logs
