Kernel Bug - 11.04 through 12.04 - Concerning Multiple GPU graphics cards

[Shaw Shipley]

I've tried to get my GTX 295 to work on multiple versions of Ubuntu, but this has failed. I know that the card itself works. I contacted NVidia and they said that it was most likely a kernel bug. I tried 12.04 off of a liveCD and that wasn't any different. I installed the proprietary drivers on a persistence file on the live USB, but that didn't work either -> That's the set-up that you have the information on.

The issue is that the kernel doesn't seem to detect both GPUs on the card properly. My lspci shows 2 GPUs, but it should show three (I currently have a GTX 460 SE and a GTX 295 in the machine, so there should be a GTX 460SE entry and two GTX 295 entries.)

Most lspci methods didn't detect anything else at all, but when I used, 'lspci -A intel-conf2', I got, "00:08.0 Non-VGA unclassified device: Device aebc:75c5". Nothing shows up on that address when I use the other detection methods and I'm not the expert, but I'm guessing that the problem is somewhere in that area.

So I suppose that the reason that I'm giving you all of this extra information is because I don't know what EXACTLY the problem is, but it seems that the kernel is unable to decide how to deal with this multi-GPU card.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.
