dmesg with gtt flush v5 patch
I've made these observations so far: The amount of reported failed chipset flushes has gone down drastically. In four test runs, only in one so far I've spotted a chipset flush failure warning. However, the GPU will still hang after a while, often without any flush-related warnings in dmesg.
I also like to add to speculations that failure rate might be related to CPU or possibly IO load. X runs for a lot longer if I just leave glxgears running by itself, but as soon as I start doing some work (Kontact, Opera, Flash plugin etc.) GPU freeze seems more likely.
