As I can see, things go wrong just after first request to device - INQUIRY. After that CAM tries to fetch details of error with REQUEST SENSE and again fails. I think you had no enabled verbose kernel messages at that moment, so I can't see some error messages I would expect there. But from this data I don't think that something is wrong with CAM. I would start digging toward umass driver (enable debug there) to find out what can be the source of these errors. Device should not return error in response to INQUIRY. PS: I can see that umass has special quirk to simulate fake INQUIRY response in some cases. I have no idea what the hell it is, but may be it is related here. -- Alexander Motin
