Only 2 out of 5 GPU's starting
We are trying to drive 9 monitors (a 3x3 array) using two Quadro (NVS 440) and one GeForce 7300GS.
Motherboard - Asus Striker Extreme
CPU - Intel 6700 quad core
OS - Fedora 7 (and briefly Ubuntu 7 - same result)
The gpu's for the first Quadro are PCI:3:0:0 and PCI:4:0:0
For the second Quadro PCI:10:0:0 and PCI:11:0:0
And for the GeForce PCI:6:0:0
It appears that only the first two gpu's found in the "ServerLayout" section are started. We have changed the layout and a different two are started.
We also tried each of pci=noacpi, pci=biosirq, noapic and acpi=off - none seem to have any effect.
For gpu's that fail to start Xorg.0.log simply states -
"Failed to initialize the NVIDIA graphics device PCI:4:0:0"
"Failed to initialize the NVIDIA graphics device PCI:10:0:0"
"Failed to initialize the NVIDIA graphics device PCI:11:0:0"
In this case the gpu's at PCI:3:0:0 and PCI:6:0:0 are starting
