Bug Description
Background:
Today I have been testing qt5.4 on krillin on vivid-proposed for allowing it to be dropped into the image. I had to install vivid-proposed onto mako so I could see which of the many issues I was hitting were qt5.4 and which were vivid.
STEPS:
1. Install latest vivid-proposed
2. Use the phone
EXPECTED:
I expect a similar stability to rtm
ACTUAL:
At various points throughout the day on bot mako (vivid only) and krillin (vivid plus silo5) the system has randomly stopped functioning. This would show as freeze where the launcher would still slide in but not much else would function. If this happens on a scope eventually the scope will restart or unity8 will. On apps they will eventually just close.
When this happens there is nothing obvious in logs and no crash files that match the app the died. So there seems to be no real clue as to what is going on.

Michal this is completely random. I have seen lockups in browser system settings unity8-dash, I've added logs from my qt5.4 siloed test device and my normal device and nothing really shows up there. I don't actually think it is unity8 but something lower down the stack. But it will lock up at least once an hour.

Only idea comes to mind is that this is another example of bug #1421009.

Thought this was a dupe of bug #1417773, but is not after all... I have not seen the symptoms you mentioned, though. At this point any help from people able to reproduce would be useful. Steps, symptoms, ideally .crash files...
