Any help is appreciated.
I'm seeing the same issue on any amd64 machine I've tried. The i386 snapshot from the same date works fine on the same machines. I'm not even able to invoke ddb from the console. I've been able to trigger it with a lot of disk activity (dd, scp or rsync of large files, etc). Sometimes they lock up immediately, sometimes it takes a fews minutes, but that always seems to trigger it for me.
