 0, 0 would be "console". Something is wrong in your /dev directory.

 The source reveals utter stupidity:
 
         if (major && buf.st_rdev != MKDEV(major, minor)) {
                 log_verbose("%s: Wrong device number: (%u, %u) instead of "
                             "(%u, %u)", control,
                             MAJOR(buf.st_mode), MINOR(buf.st_mode),
                             major, minor);
 ...
 
 The check is correct, but then it prints bits from buf.st_mode instead
 of buf.st_rdev.
