-- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to autopilot in Ubuntu. https://bugs.launchpad.net/bugs/1421009 Title: unity8 sometimes hangs on boot Status in the base for Ubuntu mobile products: In Progress Status in autopilot package in Ubuntu: Fix Released Status in libusermetrics package in Ubuntu: Invalid Status in qtbase-opensource-src package in Ubuntu: In Progress Status in unity8 package in Ubuntu: Invalid Bug description: The following gdbus call is failing with a "Error: Timeout was reached" message: gdbus call --session --dest com.canonical.UnityGreeter --object-path / --method org.freedesktop.DBus.Properties.Get com.canonical.UnityGreeter IsActive This is being seen on krillin devices starting with image 106 from ubuntu-touch/devel-proposed. It doesn't happen every time, so far today, I've seen it 3 times from about 12 tests. On the most recent failure, I grabbed a console and tried repeatedly to run the command from the shell, even after 2 hours the timeout was still being returned (after about 28 seconds). A copy of ~/.cache/upstart/unity8.log is here: http://paste.ubuntu.com/10179482/ I have 3 test cases where the problem was observed: http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-qtchooser/1/console http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-gsettings-ubuntu-touch-schemas/1/console http://d-jenkins.ubuntu-ci:8080/job/fjg-boottest/3/console In all cases, the test is using adt-run (from autopkgtest) to drive a test on the phone device. adt-run uses the above gdbus call to determine if the desktop is active. In all the examples, the device was freshly flashed. --- Timeline/Updates: 2015-02-20: libusermetrics lands, causing (apparently) this boot problem to start happening rarely. http://people.canonical.com/~ogra/touch-image-stats/106.changes / http://launchpadlibrarian.net/198152771/libusermetrics_1.1.1%2B14.10.20141020-0ubuntu1_1.1.1%2B15.04.20150219-0ubuntu1.diff.gz ”I got a symbolic trace out of all the threads. It seems to be a dbus lock between usermetrics and networkmanager bits. We suspect a relation to QTBUG https://bugreports.qt.io/browse/QTBUG-44836.” 2015-03-25: qtbase dbus update to support threads (instead of one main thread) in PPA 018 fixes the boot issue, but autopilot test suites start failing randomly. 2015-03-27: an autopilot fix fixes a simple test case, and seems to fix UITK suite as a whole, but on krillin only Currently mako still fails a lot of tests when the silo is enabled. The nature of failures is random (different tests fail on each run).
