------------------------------------------------------

Had 2 existing partitions (/home & /download) in ReiserFS format that I marked for re-use.
Created a /boot partition with ext3
Reformatted existing root partition from ReiserFS to XFS

started installation. partitioning went fine but installer crashed in beginning of "copying files" part...
