Linux, Phantom GPU: UNSUPPORTED: NV3 [PCI]

had a look into the header of my log file after the reinstall of CentOS 7 and the nV 367.27 driver ... found something interesting:

I agree with the list for GPU 0 and GPU 1; I would disagree with the GPU 2; not sure where that is coming from ...

$ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GM200 [GeForce GTX 980 Ti] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation Device 1b81 (rev a1)

Any idea where the phantom is coming from ?

folding slots are only configures for the two real GPU's; its not hurting and might be a driver glitch. The FAHClient 7.4.4 is several times reinstalled but with the same result.

interesting: just see that also in the log from this windows-oriented thread: viewtopic.php?f=83&t=28859

looks like the audio part of the card get misidentified as GPU ...

I noticed the OP has a GTX 1070, and I saw this same behavior on my Dell T7400 after I installed my new GTX 1070. It hasn't seemed to have a negative impact on Folding.
Due to the difference in slot order, mine shows GPU0 as NVIDIA:5 GP104 [GeForce GTX 1070], GPU1 as UNSUPPORTED: NV3 [PCI], and GPU2 as NVIDIA: 5 GM206 [GeForce GTX 960]

I got the unsupported: NV3 PCI message on my 1070 as well, it took a few attempts to get the card running but its now fine, driver glitch or a misreading of the audio device in the detection routines on the client?

... or a change of detection order of GPUs without repeating all of FAH's GPU configuration process or even trying to do it without GPUs.txt being updated.

As long as it stays unsupported, and the rest of the hardware is auto-detected and runs, I don't see a problem.
