Hi lists,
I gave ATA_CAM a try last night and believe I have a similar setup
(crippled hardware) in my laptop as Doug Barton's, although my
controller is ICH6M. 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`

Here's what appears in my dmesg:
atapci0: <Intel ICH6M SATA150 controller> 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.
Best Regards,
Nathan Lay
