Well this is odd... I tried following the instructions on PM tracing from https://wiki.ubuntu.com/DebuggingKernelSuspend (using systemctl suspend instead of pm-suspend), but the system hangs on resume when tracing is enabled - and this happens also when pm_test is set to "devices" (doesn't happen with "freezer").
There is no hang when tracing full suspend on 4.8.0.
