This causes SATA failures that surface as a filesystem being remounted read-only due to errors when using a disk that supports NCQ. [TEST CASE] Do a network boot install on an X-Gene system with an SSD drive that supports NCQ. The install will fail and dmesg will show the filesystem being remounted read-only. [Regression Potential] Minimal; we're turning off a feature that is known broken.
