--- Comment #7 from Alexander Motin <mav@FreeBSD.org> ---
It is not an AHCI problem.  There is some problem with PCI resources
allocation. You can see plenty of "failed to allocate" messages in dmesg
output.  Somehow what BIOS done didn't satisfy the kernel, it tries to solve
the puzzle, but fails particularly in case of AHCI controller, but may be n=
ot
only.  If BIOS update does not help, try to play with its settings, like
disabling fast boot, plug and play OS, or whatever can trigger BIOS to do f=
ull
resource allocation properly by itself.
