That's odd. My guess is that it has something to do with pages that are mapped into kernel virtual address space in the passthrough driver not getting properly unmapped when the application exits. I'm not sure how that could happen, though. I can't reproduce that behavior with tosha. Can you send me your patches to cdda2wav? If I can reproduce it, I may be able to track it down. Does the panic happen every time, or just sometimes?
