Hi mav. I didn't know what's happen. So I'll report code trace and cam related struct dump with ddb which I made. The first, cam ddb patch: show cam show cam_eb <struct cam_eb *> show cam_et <struct cam_et *> show cam_ed <struct cam_ed *> show cam_sim <struct cam_sim *> show cam_periph <struct cam_periph *> I saw gibbs'd document, and made it. If not enough, please tell me!
