Description of problem:
After running disk druid and answering all install questions, Red Hat 7.0 
says that has everything it needs to do the install.  It crashes when it 
tries to format hda8.  The install program states that this is probably a 
bug and recommends reporting it here.  This install does not produce a 
working Linux system.
