I have a similar problem with my HD4200 (RS880) since kernel 3.15
The issue is triggered by a Suspend2RAM and resume cycle.
Doing this, the last 6 lines of the screen are black and playing a video 
with vlc makes the laptop crash in a few seconds. (black screen, but with 
mouse cursor; freeze)
Workaround is to change the resolution of the screen (and back to e.g. 
1366x768). This stabilized the system until next reboot.

Do I have the same or different bug as you?
