Nonetheless, ahci detects my controller and tries to attach and fails (returns 6). No ada nodes are created and the boot process halts trying to find a root mount. Verbose booting reveals nothing special. Anything else I can do to try to reveal the problem? I tried modular ATA with the following: device atacore device atapci device ataahci device ataintel device ahci From reading the lists more thoroughly, I now have the impression that either ahci or ataahci are necessary and not both. If I remove 'device ahci' then 8-STABLE boots normally. However, I would think that if ahci failed to attach then the kernel should fallback on ataahci. If GENERIC included both ahci and ataahci, then I would never be able to boot FreeBSD let alone install it. `uname -a` FreeBSD LIGHTBULB.LOCAL 8.0-STABLE FreeBSD 8.0-STABLE #4: Thu Dec 24 02:40:23 EST 2009 nslay@LIGHTBULB.LOCAL:/usr/obj/usr/src/sys/LIGHTBULB i386 Here's what appears in my dmesg: atapci0: port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x18c0-0x18cf at device 31.2 on pci0 and the result of `pciconf -lv` atapci0@pci0:0:31:2: class=0x010180 card=0x056a1014 chip=0x26538086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = '82801FBM (ICH6M) SATA Controller' class = mass storage subclass = ATA the kernel was built from 8-STABLE tree as of last night.
