Public bug reported:

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

* 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.
