Public bug reported:
When Ubuntu is idle for some time, the screensaver appears, and when the
screen turns off, the computer doesn't respond anymore. If you turn off
the machine and try to start ubuntu again, the PC just reset
automatically. Microsoft Windows is affected too, you can't start the
system. The only way to start any OS again is recovering Windows...
