Description Klaus Kämpf 2011-03-03 18:48:17 UTC

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.19 SUSE/11.0.665.0 (KHTML, like Gecko) Chrome/11.0.665.0 Safari/534.19

systemd crashes after boot, leaving processes in <defunct>. No further services can be started, shutdown does not work.

gdb backtrace shows:

Kay, please enable OpenSUSE 11.4 on Base:System

For completeness, the i586 trace for systemd-18 that I was not able to previously provide in #678352.

> Kay, please enable OpenSUSE 11.4 on Base:System

Done.

Comment 8 Klaus Kämpf 2011-03-18 19:16:43 UTC

Thanks. And systemd-20-91.1.x86_64 from Base:System fixes the issue for me !

Kay, please submit systemd as an update to 11.4

Comment 9 Klaus Kämpf 2011-03-18 19:48:12 UTC

Hmm, the crash is gone but systemd still hangs sometimes.

Eg. "suse rcopenvpn start" hangs in
  /bin/systemd-tty-ask-password-agent --watch
with
  restart_syscall(<... resuming interrupted call ...>

Will open a separate report for this

See bnc#680958

Comment 11 Kay Sievers 2011-05-14 18:16:31 UTC

Please use the version from Base:System, it's all under heavy development, and we have no resources to support old experimental versions of systemd.
