For example: the bios returns D0 state and the real power state is D3. OS expects to set the device to D0 state. In such case if OS uses the power state returned by the BIOS and checks the device power state very strictly in power transition, the device can't be transited to the correct power state. So the boot option of "acpi.power_nocheck=1" is added to avoid checking the device power in the course of device power transition. http://bugzilla.kernel.org/show_bug.cgi?id=8049 http://bugzilla.kernel.org/show_bug.cgi?id=11000 Signed-off-by: Zhao Yakui Signed-off-by: Zhang Rui Signed-off-by: Li Shaohua Signed-off-by: Andi Kleen Signed-off-by: Len Brown --- Reading git-diff-tree failed
