Sorry for intruding in the mid-thread, but I'm getting the same kind of panic since geom-ification of ATAPI with my CDROM and burner. With last night's -CURRENT: kernel with INVARIANTS and INVARIANTS_SUPPORT does not panic, while without them just "cdcontrol -f acd0 info" 2 times (audio CD, then data CD) triggers the same panic.
