I have attempted various potential partition setups in Sabayon, all of which lead to this error. I have manually used fdisk to remove all partitions from the drive, and on another attempt to manually create the partitions - both of these attempts still resulted in the exception.

I have 2 SATA disks (SCSI emulated) which are /dev/sda, /dev/sdb (as well as a SATA CDRom); and two IDE disks. I am attempting to install to /dev/sda (no changes are being made to any other partition).

This bug is occurring with BOTH 3.4 Business Edition, and 3.4 loop3. (text below is from 3.4-loop3).
