This machine has two 3ware 7850's each with 1.1 terabyte arrays.  The related 
boot messages are:

After choosing automatic partitioning or Disk Druid partitioning, an unhandled 
exception occurs with the following:

 "An unhandled exception has occured.  This is most likely a bug.  Please
  copy the full text of this exception or save the crash dump to a floppy
  then file a detailed bug report against anaconda at

How reproducible:
Always

Steps to Reproduce:
1. Set up machine with a 1.1TB 3ware RAID5 array (8 Maxtor 160 gig drives).
2. Boot skipjack beta 2 CD-ROM.
3. Select automatic partitioning or Disk Druid partitioning.
