[ubuntu] 13.04 My laptop freezes when waking up from suspend

view story

http://ubuntuforums.org – Hi! I just installed ubuntu 13.04 on my Lenovo G580, coming from a no-troubles Mint 14 install. When I suspend my laptop, either with manual pm-suspend, closing the lid or the suspend option in unity, it suspends just fine untill I try to wake it up. Then my screen remains black, the laptop starts (i.e. if I'm watching something on youtube it starts playing) and 1-3 seconds later it crashes (i.e. youtube starts playing like a broken record). The monitor blinks white for a couple of microseconds about the same time as the laptop crashes. There are no external devices connected, no fullscreen (Hardware)
