I think that panics on I/O errors are related to that. Device going away is slightly different case, but I believe it shouldn't be generally true, except for filesystems with softupdates enabled. For the most part, softupdates don't even try to handle I/O errors - they just panic (e.g. "panic: softdep_move_dependencies: need merge code"). -- If you cut off my head, what would I say?
