Was driving around with my car, and noticed once I got back home that my clock was stuck in a previous time (~20min before getting home), and after trying to use the phone I noticed unity8 was completely stuck, but the underling OS was still running fine.
The worst here is that we're unable to notify the user about calls, as the interface is completely stuck. Another bad thing is that this could as well happen when the user is sleeping or something, without an easy way to know until he tries to use the phone.

Looking at my syslog at the exact minute that got stuck (time presented by the greeter), I wasn't really using the phone (it was trying to suspend), and I also noticed the GPS was reporting issues, not sure if related or not though: 707790] [pm_notifier_ call_chain] : there are 4 notify callbacks, event = 4 delayed_ work ret= 1 delayed_ work ret= 1 747749] [pm_notifier_ call_chain] : there are 4 notify callbacks, event = 3 747780] Freezing user space processes ...
