  ---Problem Description---
  Two or more different versions (for example 14.04.3 and 15.04) of Ubuntu DVD/CDROM is attached to any Power system then installation fails after language selection as installer tries to mount other Ubuntu DVD/CDROM which is not supposed to happen and throws below error.

  
     ???????????????? [!!] Load installer components from CD ?????????????????
     ?                                                                       ?
     ? No kernel modules were found. This probably is due to a mismatch      ?
     ? between the kernel used by this version of the installer and the      ?
     ? kernel version available in the archive.                              ?
     ?                                                                       ?
     ? If you're installing from a mirror, you can work around this problem  ?
     ? by choosing to install a different version of Ubuntu. The install     ?
     ? will probably fail to work if you continue without kernel modules.    ?
     ?                                                                       ?
     ? Continue the install without loading kernel modules?                  ?
     ?                                                                       ?
     ?     <Go Back>                                       <Yes>    <No>     ?
     ?                                                                       ?
     ?????????????????????????????????????????????????????????????????????????

  note: we used virtual dvd function from vios to attach two different versions of Ubuntu to our lpar.
  I think this issue will even occur with two or more physical dvd with different ubuntu version <-- but we have not verified this
