    When trying to mount a zip disk, the mount process gets stuck:

    [root@viper root]# mount -t ext2 /dev/sda1 /mnt/zip
    SCSI device sda: 196608 512-byte hdwr sectors (101 MB)

    sda: Write Protect is off

    At this point the mount process is unkillable.
    Also strange is that the messages are printed twice.
