I have some questions:

1. How did you add the swap space?

   Does the disklabel for your external drive (sd0) show a swap partition? Is this partition included in /etc/fstab?

2. Does the hang occur when ddb.panic is set to 0? (You may recall that if X is running and ddb.panic=1, you will never get a dump.)
3. How many hours did you run memtest86?
4. Have you installed and run the stress package? How many hours, what types of loads?
