The lack of PCI domain support on x86-64 prevents me from seeing the 
following devices on the PCI bus:

61:04.0 RAID bus controller: Silicon Image, Inc. Adaptec AAR-1210SA SATA 
HostRAID Controller (rev 02)
61:06.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X 
Fusion-MPT Dual Ultra320 SCSI (rev 07)
61:06.1 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X 
Fusion-MPT Dual Ultra320 SCSI (rev 07)

I get the following errors, unless I disable the BIOS option 'ACPI bus 
segmentation', which is enabled by default (and will be enabled on most 
future machines):

Dec  2 10:40:18 localhost kernel: ACPI: PCI Root Bridge [PCI1] (0001:40)
Dec  2 10:40:18 localhost kernel: PCI: Multiple domains not supported
Dec  2 10:40:18 localhost kernel: ACPI: PCI Root Bridge [PCI2] (0002:80)
Dec  2 10:40:18 localhost kernel: PCI: Multiple domains not supported

Full machine info was just posted in another message, subject 
"[2.6.15-rc4] oops in acpiphp".

Is this a bug?  Is this expected behavior (not implemented yet)?  A 
jump-start on tracking this down would be appreciated.

	Jeff

Based on the logic in arch/i386/pci/acpi.c (which is shared with
x86-64), it's just not implemented yet at all.

I don't know of anyone currently working on adding this support to this
code, does anyone else?

thanks,

Well, that's silly.  It should be implemented now.
