So at least the hammer_time() has a chance to initialize the console.
Do you have serial console ?  Set the loader tunable debug.late_console
to 1 and see if any NMI reaction appear.

Is there a BIOS option for 'on-chip cluster' or 'HPC computing' ?
What if you try to frob it ?

I think the only way to debug this is to add printf() lines to hammer_time()
to see where does it break.  Note that amd64_kdb_init() call succeeded,
so you can start bisect the code from there.
