With this patch I can't suspend my Samsung with:
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD]
nee ATI Blackcomb [Radeon HD 6900M series] [1002:6720]
anymore.

The backlight goes off, activity LED goes off and then nothing.
Machine is still running and other lights (power, wifi, keyboard,
touchpad) are still working. Seems like a lockup to me.
