OK, i've got a debugging kernel that includes "options  DDB" deployed to the
afflicted server, and using a serial console and voila:

Loading kernel...
/boot/kernel/kernel text=0x16a9bd0 data=0x1d2088+0x76c0c0
syms=[0x8+0x17d498+0x8+0x19a4da]
Loading configured modules...
/boot/entropy size=0x1000
KDB: debugger backends: ddb
KDB: current backend: ddb
---<<BOOT>>---
APIC: Could not find any APICs.
panic: running without device atpic requires a local APIC
cpuid = 0
time = 1
KDB: stack backtrace:

I disable APIC at the boot-time menu.
