This is indicative that the drive's firmware is incapable of coping
properly with writing on (or past) the physical end of medium.

Of course, it wants to leave the drive so that all you need to do is hit
the eject button to continue to use the drive. Note that "non-rewind"
only applies to the default action when the device is closed; it has no
other implication.

Again, the firmware didn't cope with writing on/past end of medium. It
may also be reporting incorrect status via the scsi layer.

The driver attempted to ask the drive to rewind, but because of the
confused internal state of the drive, it was unable to do so.

I'm pretty sure the only thing you would have to do is power-cycle the
drive. It is the drive that is confused, not the kernel (driver).
