Bernhard, I extracted the possibly relevant parts on /var/log/zypp/histroy into bugzilla_898913.txt (grep '2014-09' history > bugzilla_898913.txt) and grepped here. I found an update of glibc on 2014-09-11, this might not have caused the problems that appeared on 2014-09-29. For lvm2, I had installs on 2014-09-12 (2.02.98-148.1 from systemsmanagement repo) and 2014-09-29 (2.02.111-150.1 from systemsmanagement repo). So the latter might be the cause of the problem. It might be a good advice to go back to 2.02.98-0.28.18.1 from the Update repo then, I guess. OK, I did it, and it brought device-mapper-1.02.78-0.14.1.2 right along. Unfortunately, mkinitrd hangs, so I can't test it right now. Regards, Werner
