Description
Since 3.5.0 kernel (currently 3.5.2-3.fc17.x86_64), resuming from suspend or hibernation randomly fails. There is no display, and the screen flashes every few seconds (probably due to the backlight).
Hardware:
Toshiba Satellite Pro A300 laptop
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series
