I'm having quite a hard time to reproduce. The worst case I could catch was unity8 being around 15 switches/s which seems to be related to dhd_dpc. Switching off WiFi makes that go away (We probably want to add something to detach unity8 from dhd_dpc somehow when the display is off) but that doesn't seem related to this bug.
Does this happen every time for you? Or only after using a specific app, or resource? One interesting thing in your trace is that surfaceflinger is up to 70 switches too while its mostly below 2 in my case. Indicates that it might have something to do with rendering. I tried firing up lots of apps, taking pictures etc, but never reached those values. There must be something that triggers this, some specific app running, some use case on the dash or similar. Also would be interesting to see if this still happens with Mir. Can you please try to provide more detailed steps on how to reproduce?
