Here's the testing package: http://download.opensuse.org/repositories/home:/fbui:/systemd:/next:/openSUS... Please install it (zypper dup --repo X) and also install systemd-debug{source,info) from this repo to. You might need to install liblz4-1_7 from your regular repo first if it's not already installed on your setup. Reboot and start manually systemd-timesyncd, it should hang now for 30 secs. In another terminal, find out the PID of the daemon (ps aux | grep timesyncd) and attach to it with "gdb -p <pid>". You'll be able to step in through the code and see which part exactly cause the SIGSYS. Thanks ! -- You are receiving this mail because: You are on the CC list for the bug.
