Comment 19 for bug 292144

Still spamming...
 Got the CD-Rom drive working by issuing the same
echo "0 0 0" > /sys/class/scsi_host/host1/scan

 - command again after docking.

So, my undock procedure is as follows:

1. echo 1 > /sys/class/scsi_device/1\:0\:0\:0/device/delete
     # Remove CD-Rom ultrabay drive and prevent lockup when removing the computer from ultrabase
2. Push undock button at the dock

3. *** Undock by pulling lever

4. echo "0 0 0" > /sys/class/scsi_host/host1/scan
    # Prevents lockup at suspend / resume

Docking procedure:
1. Dock computer
2. echo "0 0 0" > /sys/class/scsi_host/host1/scan
    # Get CD-Rom drive back to alive.
