I searched my notes and realised that I have seen this once also with the runtime pm patch. So the fact that happened to see it more often after dropping it is likely due to changes in timing. Looking at the above log it seems like we hit a probe deferral somewhere as some resource is not available yet, and this is eventually turned into a hard failure that breaks audio as the error is propagated up the stack.
