Comment # 1 on bug 1141017 from Steffen Winterfeldt

Please attach yast logs.

To collect log files run 'save_y2logs' and attach the log file archive this
command creates (usually named /tmp/y2log-SOMETHING.tar.xz).

If the installation (more or less) succeeded and you can access the
installed system, you can collect the logs there.

Else you have these options to collect the logs from the installation
environment:

 - there's a shell running on consoles 5 and 6 during installation

 - get a console window by pressing Ctrl-Shift-Alt-x in the installer's
   graphical UI

 - if you can't reach neither or you're on a serial line or you're doing
   autoyast: boot with 'startshell=1' which will give you a shell before and
   *after* the installer runs; to continue the regular installation workflow
   just exit this shell

If you're unsure what to do, please have a look at
