Title:
  Avoton server occasionally fails to boot when using SSD disks
  connected using ahci driver

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Trusty:
  Fix Released
Status in linux source package in Utopic:
  Fix Released
Status in linux source package in Vivid:
  Fix Released

Bug description:
  SRU Justification:

  Impact:   Intermittent OS failure due to SSD disk initialisation failure
  Fix:      Upstream development
  Testcase: About once per 5000 reboots on one server. 
            If the user has several hundred servers, 
            the frequency isn't negligible. 

  ---------------------

  It was brought to my attention the following BUG:

  Avoton server occasionally fails to boot when using SSD disks
  connected using ahci driver. When this problem occurs, the disk is
  not recognized by the Linux kernel, and the server fails to boot.

  * Upstream acceptance information:

  Intel's patch has already been accepted upstream
  commit dbfe8ef5599a5370abc441fcdbb382b656563eb4
  Author: Dan Williams <dan.j.williams@xxxxxxxxx>
  Date: Fri May 8 15:23:55 2015 -0400
  ahci: avoton port-disable reset-quirk

  Refer to
  http://permalink.gmane.org/gmane.linux.kernel.commits.head/524068

  * How reproducible:
  About once per 5000 reboots on one server. However, if the customer
  has several hundred servers, the frequency isn't negligible.

  * Steps to Reproduce:
  Reboot server.
