    I'm seeing the same here:

    open("/dev/cd-rw", O_RDWR|O_NONBLOCK) = -1 EROFS (Read-only file system)
    write(2, "cdrecord.mmap: Read-only file sy"..., 89cdrecord.mmap: Read-only file system. Cannot open '/dev/cd-rw'. Cannot open SCSI driver.) = 89

    Looking at the error path, it looks like it happens in cdrom.c:

    cdrom_open() in line 747 -> cdrom_open_write() in line 708
     -> cdrom_mrw_open_write() in line 680, where there's:

            if (!di.erasable)
                    return 1;

    which is where it fails. di isn't filled correctly by
    cdrom_get_disc_info(cdi, &di)

    ie: change the "if (!di.erasable) return 1;"
    to "if (!di.erasable) return 0;" and it will work.

    Jens Axboe is listed in the changelog so he may know what's the issue here.
