The following reply was made to PR i386/135447; it has been noted by GNATS. From: Andriy Gapon <avg@icyb.net.ua> To: bug-followup@FreeBSD.org, dk@garant.ru Cc: Bruce Cran <brucec@FreeBSD.org> Subject: Re: i386/135447: [i386] [request] Intel Core i7 and Nehalem-EP new features not supported Date: Sun, 12 Sep 2010 18:52:14 +0300 First of all, the PR was created improperly - sysctl -a output is in "Fix" section for some reason. Please don't do that in the future. Second, it's impossible to tell if "C2 and C3 states should probably be available" unless we see acpidump -dt output and dmesg with ACPI debugging enabled (ACPI_PROCESSOR x ACPI_DB_INFO): http://www.freebsd.org/doc/handbook/acpi-debug.html P.S. That is, generally we expect to see C2 and C3 levels, but not universally. BIOS or BIOS configuration, motherboard peculiarities and OS supported features are among the thing that affect C2+ availability. -- Andriy Gapon
