The problem fix description is as follows:

    dasd-config: always list available DASDs for selection and configuration
    
    Previously, the DASD configuration module prompted the user to specify
    DASDs if there were more than 20 DASDs available.  If this dialog is
    shown, the user can configure DASD devices; but can only return to the
    installer through the <Go Back> button.  The <Go Back> triggers a special
    debconf return code and the "hardware-detection" dependency for this is
    not satisfied.  Later the partitioner will complain and the intermediate
    configuration file might not be copied to the target system.
    
    The second disadvantage with prompt is that the user does not see which
    DASDs are already online and configured.  See also Debian bug 666399 for
    more details.
    
    This commit removes the prompt to manually type DASDs.  The panel to
    select particular DASDs is displayed instead.
    
    Of course, there can be the case where LPARs have access to (almost)
    every device.  For this case, the solution is to use the "cio_ignore"
    kernel parameter.  With this kernel parameter you can control the
    devices that are visible to the Linux instance.
    
    For example,
    
            cio_ignore=all,!ipldev,!condev,!0.0.da00-0.0.da10
    
    ignores all devices except the console device, the IPL device, and the
    range of devices from 0.0.da00 to 0.0.da10 that might be DASDs or any
    other devices.  Note that you can change the cio_ignore settings at
    runtime, so you can later make additional devices visible.
    
    With this solution, there is no hardcoded limit necessary and the user
    can still see the list of DASDs to be configured.
