My X1 Gen 5 is having an intermittent issue coming out of standby when connected to the Thunderbolt 3 gen 1 dock (FWIW conencted via TB3 to a P32u). Windows version is 1809 with all latest updates installed. Latest dock firmware and driver installed.
Instead of coming out of standby, the laptop often restarts.
Analysis of memory.dmp using WinDbg, gives the reason as DRIVER_POWER_STATE_FAILURE ("The power transition timed out waiting to synchronize with the Pnp subsystem").
FAULTING_MODULE points to HDAudBus.sys.
This issue was not present prior to installing latest dock firmware and/or latest dock software (however, I suspect the former rather than the latter as the audio driver doesn't appear to have changed in the latest driver compared to the previous version).
