Timothy, good day.

I like to be wrong, but since at the time of the panic your disk
subsystem isn't yet initialized, you can't make crashdump. The best
way it still to get serial console working.

The first thing that you can try is to type 'bt' (without quotes)
at the 'db>' prompt and present the backtrace. The second thing
to try if you can compile your own kernel (you can do in on the 7.x
partition, just compile kernel for 8-CURRENT, set it to boot with
nextboot(8) and try to load the kernel) -- you can try to add the
following simple patch to see what device provokes assertion:

And, perhaps, the output from 'acpidump -dt' will be interesting.
