Message-ID: User-Agent: Alpine 2.00 (DEB 1167 2008-08-23) MIME-Version: 1.0 Content-Type: TEXT/PLAIN; format=flowed; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 628 Lines: 19 Hi, Linux: When I do not load the ACPI processor module, there is no high pitch noise. When I load the ACPI processor module (so I can utilize Turbo Boost), Linux makes the system emit a high pitch noise. Windows: The same system, running Windows 7 does not emit any noise. Is there something wrong with the ACPI processor module or its implementation on i5/i7 CPUs?
