Nouveau crash when booting with ATI and NVidia GPUs

[RAThomas]

System:
SuperMicro X7DBR-3 motherboard with on-board ATI ES1000 GPU (set in BIOS as primary)
2 x Intel Xeon L5410 CPUs
4 GB RAM
Add-in PCI-X NVidia GeForce 6200 GPU

During the boot process it crashes. Here's a snippet from an interactive startup:

Based on that, I figured it was choking on the NVidia card/driver. After removing the NVidia GPU from the system, F12 Live was able to boot completely.

If you put that GPU into another system, do you see the same crash? This way you can determine if the crash is due to the GPU itself or if it is due to the combination of the ATI onboard with the addon nVidia GPU. Either way, I would send the developers a bug report at bugzilla.redhat.com.

I popped the NVidia card in another computer (with no other GPUs installed) and F12 Live booted without a hitch.

I guess I'll set about gathering the information necessary for a bug report.

Thanks.
