Hi PCI/ACPI PM experts, Since Linux 4.8, nouveau switched to rely on the PCIe port driver to transition to D3cold. This however does not happen for an Acer Aspire V7-582PG (Haswell, NVIDIA GTX 750M) from Rick. Any idea why? acpidump, lspci, dmesg and other details can be found in the linked bug below.

Removing it makes things work again. I hope Bob and Lv can answer why _OSI fails. In the meantime I think we should check flags.power_resources in nouveau driver (in addition to _PR3) so that it falls back to _DSM if there are
