I used Ubuntu 12.10 on my current laptop for a couple of weeks without problems... Now there is no way to start it.
When I try to boot Ubuntu during the startup process I get this error:
[CPU0]: Package power limit notification (total events = 1)
[CPU2]: Package power limit notification (total events = 1)
[CPU1]: Package power limit notification (total events = 1)
[CPU3]: Package power limit notification (total events = 1)
And it's like I can't do anything. I'm on a Sony Vaio laptop and the CPU model is: Intel Core i7-3520M CPU @ 2.90GHz
