This the option DIAGNOSTIC that crashes the kernel. Since the console is frozen and I have no core dump in /var/crash, I set DDB so that it bt and reboots. It goes too quick for me to get a full vision of the bt but it chokes when wandering in usb_event. If that may have something with it (since all USB attached devices are keyboard and mouse), PCKBD_CNATTACH_MAY_FAIL is not set.
