Public bug reported:

After upgrading to Ubuntu 12.10 my system keeps crashing. The GUI
dissapears and I get to a terminal screen with these messages:

Oct 21 16:18:53 ultraviolence kernel: [ 6626.273022] CPU6: Package power limit 
notification (total events = 9)
Oct 21 16:18:53 ultraviolence kernel: [ 6626.273024] CPU3: Package power limit 
notification (total events = 9)
Oct 21 16:18:53 ultraviolence kernel: [ 6626.273026] CPU7: Package power limit 
notification (total events = 9)
Oct 21 16:18:53 ultraviolence kernel: [ 6626.273028] CPU5: Package power limit 
notification (total events = 9)

It is possible to change to another terminal with ctrl+alt+f1 and log in and do 
stuff.
I'm attaching syslog and kern.log of a crashed session.

This issue does not happen if a I use kernel 3.2 that came with Ubuntu
12.04.
