Subject: [PATCH] ACPI suspend: Execute _WAK with the right argument
Date: Wed, 13 Feb 2008 00:32:16 +0100 [thread overview]
Message-ID: <200802130032.17636.rjw@sisk.pl> (raw)
From: Rafael J. Wysocki <rjw@sisk.pl>
The _WAK global ACPI control method has to be called with the
argument representing the sleep state being exited. Make it happen.
Special thanks to Mirco Tischler <mt-ml@gmx.de> for reporting the
problem and debugging.
