<pre>I suspect this might be gnome being "helpful" and automagically suspending the
machine when the display blanks.
Jani, wasn't there some kind of hidden knob for this that you found on your
laptop?
Anyways, you may want to try to disable the gnome display power save thing, and
just manually turn off the screen with 'DISPLAY=:0 xset dpms force off'. And to
make doubly sure maybe even eliminate gnome from the equation and just fire off
a bare X server, and then do the xset thing. If that doesn't hang then this
doesn't look like anything to do with i915.
Well, there is still a slight chance that it might hang somewhere in i915 while
suspending the machine. But it's not clear that there is even a proper hang
anywhere. It's also possible the machine just refuses to wake up after being
suspended.</pre>
