Subject: [PATCH] acpi: handle ACPI0007 Device in acpi_early_set_pdc
Date: Thu, 09 Sep 2010 18:56:59 -0700 [thread overview]
Message-ID: <4C89906B.1050406@kernel.org> (raw)
When bios switch to use Device object instead of Processor statement.
the SSDT for Pstate/Cstate/Tstate can not be loaded dynamically.
So try to scan ACPI0007 in addition to Processor.
this fix regression: 2.6.32 is ok.
