I've got a Samsumg s9 (RAM: 4gig, I5, solid state hard drive). And it is just amazing. I just installed ubuntu studio 12.04 LTS. And for some reason every once in a while it freezes completely (I can't even use the ctrl+alt + F* terminals) and I have to do a hard reboot. As you can understand this is very frustrating since I cannot rely on my laptop.
Can anyone please help me ?
