[PATCH v4] pci: prevent putting nvidia GPUs into lower device states on certain intel bridges
...IMO more likely is that the AML does something which > cannot be done to a device in a PCI low-power state. BTW, I'm wondering if anyone has tried to skip the AML instead of skipping the PCI PM in this case (as of 5.4-rc that would be a similar patch to skip the invocations of __pci_start/complete_power_transition() in pci_set_power_state() for the affected device).

Too bad it did not help :( I suppose there is no change if you increase the delay to say 1s?
