Rewriting Intel PCI bridge prefetch base address bits solves nvidia graphics issues
...n some way.
After a lot of experimentation I found a workaround: during resume,
set the value of PCI_PREF_BASE_UPPER32 to 0 on the parent PCI bridge.
Easily done in drivers/pci/quirks.c. Now all nvidia stuff works fine.
As an example of an affected product, take the Asus X542UQ (Intel
KabyLake i7-7500U with Nvidia GeForce 940MX). The PCI bridge is:
00:1c.0 PCI bridge [0604]: Intel Corporation Sunrise Point-LP PCI
Express Root Port [8086:9d10] (rev f1) (prog-if 00 [Normal decode])
Flags: bus master, fast devsel, latency 0, IRQ 120
Bus: primary=00, secondary=01, subordinate=01, sec-latency...
