The controller used is a atapci0: <VIA 6420 SATA150 controller> port 0xfe00-0xfe07,0xfd00-0xfd03,0xfc00-0xfc07,0xfb00-0xfb03,0xfa00-0xfa0f,0xee00-0xeeff irq 20 at device 15.0 on pci0 However AHCI with ATA_CAM does not work. I have to use 'ata' additionally in the kernel to have access to my disk. The device nodes used for the partitions are all prefixed with ada*. lrwxr-xr-x 1 root wheel 6 Apr 9 10:21 /dev/ad4s1 -> ada0s1 lrwxr-xr-x 1 root wheel 7 Apr 9 10:21 /dev/ad4s1a -> ada0s1a lrwxr-xr-x 1 root wheel 7 Apr 9 10:21 /dev/ad4s1b -> ada0s1b lrwxr-xr-x 1 root wheel 7 Apr 9 10:21 /dev/ad4s1d -> ada0s1d lrwxr-xr-x 1 root wheel 7 Apr 9 10:21 /dev/ad4s1e -> ada0s1e lrwxr-xr-x 1 root wheel 7 Apr 9 10:21 /dev/ad4s1f -> ada0s1f When compiling the kernel without 'device ata' and just leaving 'device ahci and options ATA_CAM' it does not work.
