[Bug 1418707] Re: Vivid Random lockups

 

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.

Title:
  Vivid Random lockups

Status in unity8 package in Ubuntu:
  New

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.
