Comment # 8 on bug 1209497 from Stefan Hundhammer

This openQA test does not collect y2logs before the reboot, so I don't see a
way to investigate this any further.

Is it a problem with the console being redirected to a serial port? A kernel
crash? A bootloader failure? From what point on should the openQA framework
give us any kind of feedback if any of those things happened? I don't know.

What we do know, however, is that the YaST installation did not throw an error,
and it didn't crash unexpectedly. So I don't believe that this is a YaST bug
until proven otherwise.
