it might be related, it might be not since I am using a different card 
but still the 915 driver.. but while running both 7.0 release and 
current, i get a message that an interrupt storm. WHile running a 
lock-debug kernel, the kernel crashes.

drm: GPU HANG: ecode -1:0x00000000, reason: Command parser error, iir 
0x00008010, action: continue
drm: GPU hangs can indicate a bug anywhere in the entire gfx stack, 
including userspace.

drm: HPD interrupt storm detected on connector DP-2: switching from 
hotplug detection to polling


have you seen something like this in your boot messages?
