What's the way to debug a kernel that hangs so early that you can't printf
or drop into ddb? I guess that's a phenomenon quite common for a new port
or changes to locore.s (or whatever that's called today), but it's completely
new to me.

I have virtually no clue about PeCee hardware. At the point the kernel is
started, are BIOS routines still available?

If you use -current, I think it may hit the following issue.

Could you try the patch in PR?


Thanks,
