    Yes. That would explain a lot.

    The ide-scsi thing never uses "cdrom_get_last_written" crud. It just uses
    the regular READ_CAPACITY command (0x25).

    Which is what ide-cd.c will fall back to as well ("cdrom_read_capacity()")
    but I think it should _start_ with that rather than fall back on it.
    That's the simple case, after all.

    Does it work if you change the order of those two things in ide-cd.c (or
    just remove the call to "cdrom_get_last_written()" entirely, so that it
    always just does the sane thing).
