The problem seems to be with the runtime power management. MHI pci driver is moving the device in low power state (suspend) when not used for ~2s. And here device resume fails. How the EM120 is connected to your machine is it via M2 laptop port or are you using a 'dev-board' with PCI-express slot? can you share the firmware version? building mainline right now and going to test that on my side.
