    At this point, I don't think its a configuration problem, but rather a bug in the driver.
    What platform and what driver version?

    Edit: Only reason I ask is because I know if I yanked my 5870 out or possibly just took the physical bridge off I'd get cross fire to work. However I'm not doing it lol
    and why should I when I have all 3 GPU's singing fine in Windows 7 playing Skyrim getting over 120fps(have vsync on with 120hz monitor).

      I have an ASUS Sabertooth AM3+ AMD 990FX motherboard with 2 Sapphire Radeon HD 6850 cards connected with physical bridge.
      I am using Catalyst 12.1 drivers on Debian 6.0 (amd64)

        Hmm maybe the chipset we have isn't properly supported as I also have a 990FX chipset only on a Crosshair Formula V but two cards should defiently work as far as the BUS ID's only time
        I've seen it come up blank(0:0:0) like that is when the screen portions aren't configured properly.

        In other words you can't have a "Big Box" or Multi-Display Desktop at the same time as crossfire in Linux.

          Can you post an example xorg.conf file that defines this setup?
          I just want to make sure I have that correct.

            Sure here is a very basic bare minimum example.


            Code:
            Section "ServerLayout"
                    Identifier     "aticonfig Layout"

            EndSection
            
            Section "Module"
            EndSection
            
            Section "Monitor"
                    Identifier   "aticonfig-Monitor[0]-0"

            Edit: I purposely didn't setup the xorg.conf with the 5870 card involved wanted to keep it as close or similar to what your's should look like. As you can see device 0 is only using a display "Option "Monitor-DFP2" "0-DFP2""
            It seems they changed a few things as well with the new 12.2 drivers I mess around with it later. Right now have some stuff to do

            Used:
            Code:
            aticonfig --adapter=0,1 --initial
            In my case I have to.
            Code:
            ~ $ aticonfig --lsa
            * 0. 03:00.0 ATI Radeon HD 5900 Series

                ohhh well
                Did you make a chain with " --cfa, --add-crossfire-chain" also make sure your xorg.conf is setup correctly.

                  Works

                  So not sure what has changed in the newer catalyst drivers(12.6) but it seems I at least got the 5970 crossfire working but not with the 5870 in tri-fire maybe in the future they can get it fixed.
                  I doubt it in Catalyst 12.8 though lol.

                  My adapter info:
                  Code:
                  ~ # aticonfig --lsa
                  * 0. 03:00.0 ATI Radeon HD 5900 Series
                    1. 04:00.0 ATI Radeon HD 5900 Series
                    2. 0b:00.0 ATI Radeon HD 5800 Series
                  
                  * - Default adapter
                  As it seems I didn't even add any chains myself I simply setup a new xorg.conf with:
                  Code:
                  aticonfig --adapter=0,2,1 --initial
                  Then I went into /etc/ati and removed the current "amdpcsdb" then copied from the default "amdpcsdb.default"
                  Code:
                  cd /etc/ati
                  rm amdpcsdb && cp amdpcsdb.default amdpcsdb
                  I realize just "cp /etc/ati/amdpcsdb.default /etc/ati/amdpcsdb" would have been suffice but just wanted to illustrate it that way.

                  NOTE: Keep in mind any changes to the "amdpcsdb" must be done when X isn't running as when you shutdown/restart X it re-writes to the amdpcsdb file.

                  Then I booted into X and loaded the AMDCCC (Administrative) let it set the displays properly being I have only one Monitor setup it changes the config to a single display from multi-display.
                  Restarted X and viola it had automatically setup crossfire chains and set it to enable first time I saw this done.

                  Code:
                  ~ # aticonfig --lsch

                  Now I don't know why it's listing the 3rd entry there I just think it's a print error and getting confused with the 3rd GPU. Never the less GPU0 and GPU1 are crossfired.

                  One thing I know for sure is that you can't have AMD IOMMU Support enabled in the Kernel "CONFIG_AMD_IOMMU" crossfire simply won't work if it is, now I'm not sure if that is Catalyst Issue or Kernel issue.
                  You can have IOMMU Hardware Support (IOMMU_SUPPORT) enabled though this is fine I also have it enabled in my BIOS this doesn't seem to break crossfire.

                  My setup consists of a Asus Crosshair V Formula with HD RADEON 5970 (Hemlock) and RADEON HD 5870 (Cypress XT) below I will paste my lspci -k and xorg.conf.
