The system will be hold by the infinite loop in ACPI method IPCS and then the PCIe root port of NVIDIA gpu fails the power transition from D3cold to D0. It's because the display connector hotplug event not handled properly in graphics drivers and the system will freeze for > 30 seconds to wait for ACPI method IPCS to exit.

Connect either Dell WD19SC/DC/TB docking station(USB Type-C) to the system. 2. Connect to external display to HDMI/DisplayPort of the docking 3. Suspend the system 4. Unplug the USB Type-C connector which connects to the system 5. Press power button to wake up the system 6. Check if the internal/external display come back within 10 seconds. [Results] Expected: System works with the internal/external display Actual: System takes > 30 seconds to get back the display.
