The machine's keyboard and console switching is dead and the login in
process drops the wifi but I think I can get in through ssh over
ethernet. The power button does make it shutdown cleanly and there is no
oops. I'll try and get backtraces later, probably tonight.

I have a question though, where in the i915 driver is
master_priv->sarea_priv assigned a value? or master_priv->sarea for that
matter? As far as I can tell those pointers are never assigned values?
Is there a drm_getsarea() call missing? 

Perhaps my patch fixes things since sarea and sarea_priv are given a
value?

Cheers,
