Title:
  ahci-xgene falsely advertises NCQ support

Status in “linux” package in Ubuntu:
  In Progress
Status in “linux” source package in Trusty:
  Fix Committed
Status in “linux” source package in Utopic:
  In Progress

Bug description:
  [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.
