(Apparently, Linux got C3 support on a quick boot with a live CD.) I would say that your C2 state has too high entering latency (at least from point of my C2D of C1/1 C2/1 C3/57). May be you have some C2E hack enabled in BIOS, which makes C3 useless and BIOS hides it? FreeBSD receives all info about supported states from ACPI BIOS, so ACPI can report whatever it wants about set of C-states. -- Alexander Motin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
