Can you add a line
  set debug.acpi.disabled="acad
in /boot/loader.conf and see if it stops hanging?
and maybe the following(one at a time)
  set debug.acpi.disabled="thermal"
  set debug.acpi.disabled="acad thermal"

When set each option my system fully boots off line and on line!

as I see messages from thermal code in your dmesg log just after
the "start_init: trying /sbin/init".

Does your laptop always lock-up at the same place?

Yes it does alway lock-up at the same place, the only real difference I see in the dmesg when booting off line is that my thermal profile changes to economy.

I used to see my laptop
lock-up too when it's not plugged, but it locked up in various places;
sometimes it didn't lockup, sometimes it didn't even make it into
single-user mode, sometimes just before starting X. Plugging on and off
while my laptop was running almost always locked it up. I used to see this
with older ACPI code but not recently. I'll try reproducing it with my laptop.

Thanks for digging into this one, if I can be of any assistance please say so!
