Public bug reported:

[IMPACT]
ahci-xgene doesn't support NCQ but it sets this flag. 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.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete
