This is a wide range, so it's difficult to say exactly where things are going wrong. I will say that generally FreeBSD is not expected to work on the D1; as far as I know you are the first to try it. This hardware has some quirks requiring special support, which we are entirely lacking. Specifically, there is one related to virtual memory management, which requires custom (spec-breaking) bits in the page tables to be set, to properly specify the attributes of physical and device memory. This _may_ have something to do with why it is failing where it is. It would take a motivated party to add the support required for this SoC, and I'm not aware of anyone currently taking this on. This board has caused some headaches in Linux-land for the same reasons, but there are more hands to do the work there. I just want to set the expectations properly :) If you wanted to debug this further, you might rebuild the kernel after adding 'options EARLY_PRINTF' to the config file, as this should enable a couple early outputs and narrow down the search slightly.
