For others: the last few lines in the kernel log are:

acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on acpi0
acpi_hpet0: vend: 0x8086 rev: 0x1 num: 3 hz: 14318180 opts: legacy_route 64-bit
Timecounter "HPET" frequency 14318180 Hz quality 900
acpi: wakeup code va 0xffffff848311d000 pa 0x4000
ahc_isa_probe 0: ioport 0xc00 alloc failed

I don't see any indication of AHCI problems here (or AHCI at all).
ahc_isa_probe is for the ahc(4) controller -- Adaptec SCSI.

A verbose boot might be more helpful.
