Bug Description
That's not happening all the time but has been reported by several users on the list and I also hit the issue

This happened previously, reported as bug 1378126, maybe it's come back again?
| Sebastien Bacher (seb128) wrote : | #3 |
yeah, that's likely a different issue though, emails on the list suggest an high cpu load due to wifi discovery there...

It's not the same as bug 1378126. That one was because the focused app was woken up when the greeter was hidden, thus catching up with everything while the lockscreen was visible. The fix was to only wake up the app when the lockscreen was unlocked. That is still the case, I just verified.
So very likely something else triggers a cpu intensive task when the phone wakes up from deep sleep, processing things while the lockscreen is there.

I'm getting this behaviour. Running "top" shown dbus-daemon consuming 33% of CPU time. Is that normal?
