Thanks, doing some tests with git HEAD and this patch. As far as chipset flushes go, I'm at slighly over 4.5M flushes right now. Since this is about four times as long as the machine usually lasts without freezing, I'd conclude that the fix is pretty effective.

As for failed chipset flushes, dmesg records three occurences now after about one hour of glxgears and various other tasks.
