It was running 7-CURRENT from a week before the branch on amd64 with an LSI SAS controller. The interesting thing is the nearly all -- it destroyed all the partitions with softupdates on, and left all the ones with softupdates off unharmed. Maybe this is useful? -Nathan (I'm not subscribed to this list, so cc on replies if you want me to see them)
