Describe the bug

I'm trying to use the open version of Nvidia driver because of RmInitAdapter failed! issue with the proprietary one, but I'm getting errors from the kernel. In the attached logs artifact it's around 7000 line.

To Reproduce

Boot the latest Fedora kernel with the open source driver and eGPU.

More Info

eGPU works with Windows and with nouveau driver.

Start with the attached nvidia-bug-report-535-open.log.gz, especially the area around line 7000, and reproduce by booting Fedora 38 with the open driver and the eGPU. Compare the Chipset Setup Function Error and related display errors with the report that the eGPU works under Windows and nouveau; done means the eGPU loads without these errors.
