The system locks hard without a memory dump. There are absolutly no logs or errors reported when the system goes down. All I know for sure is that it happens with the SMP enabled kernel no matter which processes I am running. I doesn't happen with the same hardware and software when running with SMP disabled. I know the AMD 'MP' processors are fairly new, has the SMP support in FreeBSD been designed to support this family of processors?

When the system locks up, can you invoke the kernel debugger (ddb) by pressing Ctrl-PrtScr? (You need a kernel compiled with 'options DDB' for that.) If you can, could you set a crash dump device by setting the dumpdev variable in /etc/rc.conf to a suitable partition (your swap partition would probably do fine, if it is at least as large as your machine's physical memory), then, upon crashing, escape to ddb and give it a 'panic' command? Then you should follow the instructions at http://www.FreeBSD.org/handbook/kerneldebug.html and post the information obtained from the crash dump. If this is a SMP-related lockup, it is a bit unlikely that the system would allow you to invoke the debugger; still, it would be worth a try..
