You want to change the performance/economy settings in rc.conf. Man 5 rc.conf The defaults were changed between 5.2.1 and 5.3: src/etc/defaults/rc.conf:revision 1.206 date: 2004/05/29 04:52:37; author: njl; state: Exp; lines: +1 -1 Throw the switch and enable use of the lowest idle states while online in addition to offline. This can be overridden in /etc/rc.conf if it causes trouble although this has been stable since 2003/12. I have no idea why C3 is unstable on your machine. Please try overriding this with something like this and see if it helps: performance_cx_state=HIGH economy_cx_state=HIGH -- Nate
