I failed to trigger the bug without rebooting between the enable/disable steps, so the unit files also continuously reboot the system until the bug shows up. To see the bug, I performed the following steps (within VirtualBox, hosted on openSUSE 13.1, x86_64): * install openSUSE 13.1 from DVD, with minimal server selection (4 CPU cores, 48GiB HDD, 768MiB RAM, no separate /home) * install NetworkManager with zypper, thereby remove patterns-openSUSE-minimal_base-conflicts At this point it is a good idea to create a vbox snapshot to be able to restore the current state after experiments. * copy bug865188.{service,timer} to /etc/systemd/system * enable bug865188.timer and debug-shell.service * reboot (the vbox) The vbox will now enter an endless reboot cycle, and it logs its actions into the file /root/bug865188.log. To watch the progress, one can create a vbox shared folder and make this file a symlink into said folder. Then one may watch the log file on the host while the machine continuously reboots. On my vbox test machine, something between 34 and 209 cycles are needed to trigger the bug. Once the bug got triggered, the cycle ends (systemd can't initiate a reboot anymore). The debug-shell on vt10 permits to inspect the system. I also attached the output of journalctl, of dmesg, and a core file I found in the root directory after the bug occured. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
