I am running 10.10 Desktop version and it has been working for a month or so. All of a sudden, I am getting "random" freezes from 5-15 minutes after startup. The system never comes back and I have to reboot. I am an Ubuntu/Linux newbie, so I don't know how to begin to diagnose the problem. Another thing to mention is that I am running Linux inside of VirtualBox 4.0.4.
Are there logs I can checkout? Anything else I can consider? I can provide more level of detail if needed - I just don't know what else is relevant. Thanks!
