I had a nightmare problem with a newly compiled kernel not booting. The problem may have been with the command mkblkdevs of nash but in any case I did extensive web search on the AHCI controller that I had in both a notebook and a desktop computer, both of which had the booting problem.
One example of the controller is Intel ICH9M-E/M SATA AHCI Controller In web postings there were many problems attributed to this controller. It does RAID 1 using software. The Linux driver was (is?) a "work in progress" from what I gather reading web postings. Dr. A.J. Travis wrote:

Hardware RAID 1 should be simple and reliable. But when the RAID controller relies on software running on the O/S, then it might be better to use Linux software RAID.
