Bug detailed description:
-------------------------
When I do “ echo mem >/sys/power/state” ,the memory can be suspended. And Then I press power button to wake up memory, the Memory can be waked up normally. However, An error “[drm:pch_irq_handler] *ERROR* PCH poison interrupt”message appears in the terminal. This issue occurs in Sugarbar rev09 GT2 every time. But never have occurred int Sugarbar rev09 GT1.
It’s kernel regression.
Reproduce steps:
----------------
1. Don’t start X
2. echo mem>/sys/power/state
3. press power button to wake up
