http://bugzilla.suse.com/show_bug.cgi?id=929224 --- Comment #2 from Christian Hueller <chuller@suse.com> --- this bug very much looks like http://lists.freedesktop.org/archives/systemd-devel/2015-February/028510.htm... so i tried what was suggested in message 2: ---------------snip-------------------- To make this work, can you reproduce the issue, then use gdb: 1. Type "gdb" to start it 2. Type "attach 1" to attach to PID 1 3. Type "b source_dispatch" to set a break point on the source_dispatch function 4. Type "c" to continue execution 5. This should then break on the next execution of the source_dispatch function 6. This should happen immediately, after all PID 1 is busy looping around a timer. Use "p s->description" to get a short description string for the event that is being dispatched. In fact, please use "p *s" to get all data about the event, and paste it here. Thanks! Lennart ---------------snip-------------------- However, when doing so, i get this: ---------------snip-------------------- skaro:/suse/chuller # gdb GNU gdb (GDB; openSUSE 13.2) 7.8 Copyright (C) 2014 Free Software Foundation, Inc.
