Hi, I have problem with very basic device. Device pci-e not resume from suspend. Only sleep.

I have a problem with anyone interested in it, because everyone thinks it is the fault of the device drivers themselves. But this is not a problem.

This device is a basic device. I've already installed drivers on various hardware and it has always been ok, but not this time.

I'm an electronics technician. After diagnosing what I managed, in my opinion the device remains asleep.

Where does my application come from?
I have multiuser mode and I do not use this device. After suspend lspci and lshw show normal data. Normal data is in /proc/bus/pci/...
Next suspend and resume, and...
lspci see hardware, but is error
lshw see hardware as undefined device
data in /proc/bus/pci/... is only 0xFF
Hardware sleep, not work, not ready. This is bug.

But since the problem concerns the graphics card in the configuration with the second default Intel card, everyone thinks that this is another driver problem as always and nobody wants to take a look at it :(

The problem is easy to recognize. On the internet, I've seen a lot of unresolved problems in which I could see exactly what I found.

My hardware is Lenovo with NVidia and Intel Graphics. Problem is with NVidia. I tested Z710 and Z50-70. The first symptom of the problem is lspci in multiuser mode (or when is XServer with intel graphics). After suspend NVidia have e.g "rev. A1", after resume is "rev. FF". Next symptom lshw and /proc/bus/pci/...
When system started with normal NVidia driver, system not resume and halt, only black screen.

There are many examples on the Internet with unsolved problems e.g https://www.lwks.com/index.php?option=com_kunena&func=view&catid=21&id=124374&Itemid=81
