My recent kernel does the same on two "FreeBSD 10.0-CURRENT #1 r234309: Sun Apr 15 14:14:11 CEST 2012" boxes. Both boxes in common is they are attached to a Dell UltraSharp U2711 screen which does have a built-in USB/MMC hub. I realized that it was possible to log into my lab's box from remote when I'm not in the lab and that is usually coincidentally with a switched off screen. This morning I loged in from home, loged out and got to the office, switched on the screen - and reboot! I wasn't able to get the system running again, it always got stuck in a Fatal trap 18: integer divide fault while in kernel mode Unplugging the screen's USB hub makes the system booting again! Following is one of the last logged messages from the kernel, I don not know whether this is usefull looking for the problem.
