>Description:
The motherboard has a NVIDIA MCP67 AHCI SATA controller

Motherboard is
        Manufacturer: XFX
        Product Name: MI-A78S-8209
        Version: Ver1.1

Periodically, the disks will disappear with this log and then crash at times or fail to detect any disks.

It's also impossible to install FreeBSD 9 because of this error and FreeBSD 9 will not detect any disks.

This happens on all all 3 motherboards I have that are identical to this one.

>How-To-Repeat:
Installing FreeBSD 9 will keep printing the error until it gives up and fails to detect any disks.
