--- Comment #145 from Chris Wilson chris@chris-wilson.co.uk 2012-04-16 04:27:15 PDT --- I've put some recent patches into http://cgit.freedesktop.org/~ickle/linux-2.6/commit/?h=845g which makes my 845g much more stable, though I'm still getting spurious GPU hangs under memory pressure. In that regard SNA is performing better (not only to being a more complete acceleration architecture) as it is thrashing the GTT far less.
