Default CentOS 5 dual GeForce 8600 GT

We have a dual opteron based system running 32bit CentOS 5. Running with dual GeForce 8600 GT. We have 4 Dell 30" monitors connected, unfortunately we only ever get one GPU working, therefore powering 2 of the screens. Ultimately we wish to have 3 cards and 6 screens.

The xorg.conf file section is shown below:-

EndSection

To overcome the vmalloc issue grub.conf is setup as;-

CentOS (2.6.18-8.1.8.el5PAE)
root (hd0,0)
uppermem 524288
kernel /vmlinuz-2.6.18-8.1.8.el5PAE ro root=/dev/system/root pci=nommconf vmalloc=396MB
initrd /initrd-2.6.18-8.1.8.el5PAE.img

We are running the latest driver 100.14.11, the nvidia bug report is attached.

In addition, if we replace the 8600 cards with two 7900 it works perfectly, even with the vmalloc setting removed.

Does anyone have any ideas?

The errors we are seeing are :-

Default Re: CentOS 5 dual GeForce 8600 GT

In your X log, I see:
(WW) NVIDIA(0): TwinView requested, but only 1 display devices found.
(EE) NVIDIA(1): Unable to find available Display Devices for screen 1.

It looks like most of your display devices aren't being detected at all. Are they directly attached to the graphics cards, or are you using an intermediary device?

Also in dmesg of the bug report I see:
PCI: Failed to allocate mem resource #6:20000@c0000000 for 0000:06:00.0
PCI: Failed to allocate mem resource #6:20000@e0000000 for 0000:82:00.0

Those are the locations of the two graphics cards, and suggest a BIOS bug. Have you verified that you're using the latest motherboard BIOS?

Hi netllama

Thanks for your response. I had upgraded to the latest stable BIOS release, there was a later beta release, which I have now installed. This has resolved this issue.

Thanks
