Seems this is now fixed in the mainline kernel. I also confirmed that v4.14-rc6 fails to resume. Most likely Rafael's revert of the following two commits fixed the issue: 5ba257249e9c ("Revert "PM / QoS: Fix default runtime_pm device resume latency"") d5919dcc349d ("Revert "PM / QoS: Fix device resume latency PM QoS"") Regards, Tony
