--- Comment #3 from Peter Wu <peter at lekensteyn.nl> ---
When the nouveau driver is loaded, runtime PM for the Nvidia PCI device
(01:00.0 in your case) should be enabled. Without pcie_port_pm=off this will
also enable runtime PM for the parent device, a PCIe port.

Any reason why you boot with acpi_osi=! acpi_osi=Linux? If you want to prevent
a lockup that occurs with Clevo P6xxRx models, try acpi_osi="!Windows 2015"
(see https://bugzilla.kernel.org/show_bug.cgi?id=156341)
