Do you have serial console ? Set the loader tunable debug.late_console to 1 and see if any NMI reaction appear. > === > > This is verbose boot. > No reaction to ~^B, NMI. > > Same for head and 10.3-RELEASE. > > Hardware is Supermicro X10DRi, Dual E5-2650v4, 256GB RAM. Is there a BIOS option for 'on-chip cluster' or 'HPC computing' ?

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.
