Indeed, Esc shows the startup lines flashing by, too fast to read anyting though. I reinstalled it and then the message kept being displayed on startup and shutdown, but the system did not hang on it. However after installing some updates and software, the same lockout occured: this is apparently one of Rosa's lesser products. On the other hand, I have been using their Marathon2012 LTS for some time now with no trouble at all. I have now installed Mageia2 on the laptop, so far without problems, works fine.
