I would like to inform you that I just finish the installation of Ubuntu 12.4 on my DC3217IYE. I did not have a problem and it is working fine.
I did not download drivers since I was just trying to duplicate your issue. I installed the OS on AHCI mode on BIOS.
You may want to forward your inquiry to Linux* Ubuntu distribution support community for further assistance since this is an operating system that we do not support.
