Bug#659986: installation-reports: Netboot fails with mdadm error at partition manager
thanks for testing and for your feedback.
Can you test if this happens to your system only with the netboot method
or if also happens to your system with netinst  ?
Can you share the installation log  (gzipped please) before you try
other installation ?
