Public bug reported:

problem found
With MCP7A Controller Nvidia chipset (ATOM / ION Platform), mini-ITX
AMI BIOS -> N1012WZT.rom - release12 October 2009

Creates many problems connecting hard disk SSD OCZ Agility 3
Consequent block of the entire operating system and reboot and errors created 
the filesystem (ext3-ext4).

Total instability detected using the motherboard:
Zotac IONITX FE - (MCP7A Controller Nvidia chipset)
SSD 60GB OCZ Agility 3 - (Sata Cable Short - Bios Settings AHCI)

Using Hard Disk to Another Motherboard:
ASUS P5E - (Controller Intel ICH9 Chipset)
ASROCK PV530 - (Chipset - VIA VX900)
I have not found any error in communication and / or instability of the 
operating system.

Can I assume that it is a form of Kernel Bugs, which manages the
Controller MCP7A Nvidia chipset.

Please you to make changes readily resolutive this drawback ...

Best Regards
