pcieport Non-Fatal error

[jzness]

Hello,

I have been dealing with an issue recently ever since I added a secondary video card to my machine. I am not sure if it has to due with it being an identical card or what but I continuously get this error non stop 24/7. It makes it difficult to see the actual syslog events because its just over run with these errors. The video cards are GForce GT 730's

I have seen some reports online of similar pciport errors that just consistently flood the syslog, but nothing quite like what I am seeing. I have seen some ways to hide these error alerts but am more curious what is causing this/how I can resolve it.

Here is my lspci list -> lspci - proxmox issue - Pastebin.com

Has anyone experienced this before? Could it be due to the identical GPU's or something different? One GPU is passed through to a Windows 11 VM, the other is just being used by Proxmox I assume. I had to get the additional card because I was having trouble passing through the 1 gpu without proxmox taking it for itself.

Thank you ahead of time for any help!

Have you tried this work-around for that?

I have no idea how to fix the AER errors, sorry. Maybe you can find some more informative errors than "Multiple Uncorrected" early after a reboot? When do those errors start; at boot or when starting the VM with passthrough? Which GPU of the two is passed through and which is used by Proxmox? What do your IOMMU groups look like and what is the VM configuration file?

Ah ha! So I actually did resolve it I believe, but it wasn't due to the duplicate vendor/device ID's. I initially went ahead and assigned the second card to a dummy VM, which seemed to resolve it for a few minutes, but then it started again.

Turns out -- it appears to have been due to me having the nvidia drivers still on blacklist when I did an initial passthrough config previously (when I just had 1 card). Once I removed those drivers (I assume the nvidia driver specifically) and rebooted, I am no longer getting those errors.

Thanks for those resources, they will def may be useful for me in the future depending on what I end up doing with the second card.
