Subject: High pitch noise when ACPI processor module is loaded.
Date: Sat, 23 Jan 2010 10:48:50 -0500 (EST) [thread overview]
Message-ID: <alpine.DEB.2.00.1001231046080.1064@p34.internal.lan> (raw)
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?
Justin.
