> had some trouble getting this, not sure if its valid by the time I did gdb of usc while froze
Unfortunately the command used in gdb was 't a a b' which inserted breakpoints in all threads, instead of the correct 't a a bt' (note 'bt' vs 'b') which would print the backtraces :) So the log is not very informative. The lsof output shows that unity8 has *not* exhausted its fd namespace, so this is not an instance of https://bugs.launchpad.net/bugs/1495871. lsof was not run as root, so we didn't get fd information about USC (which runs as root). For reference, the exact invocations to use to get all the information next time this occurs: $ sudo gdb -p $(pidof unity-system-compositor) (gdb) thread apply all backtrace full $ sudo lsof -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity-system-compositor in Ubuntu. https://bugs.launchpad.net/bugs/1491566 Title: unresponsive shell including power button doesn't blank/unblank display Status in Canonical System Image: Confirmed Status in Mir: In Progress Status in unity-system-compositor package in Ubuntu: In Progress Bug description: Note: based on descriptions we spawned bug 1495871 to cover cases where the power button still works, this bug will only be for cases where the ui input is frozen as well as the power button being unresponsive RC proposed MX4 r100 This happened twice in the last two days Receive an incoming text Screen turns on and notification is shown notification goes away try to interact with the phone and nothing works another text message is received and the notification is displayed Adding incoming calls as also suspected to be triggering the issue Note this has been impossible to reproduce, and in use only happens very rarely To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1491566/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
