Upstream (xf86-video-intel) bug was just closed fixed: --- Comment #120 from Chris Wilson <ch...@chris-wilson.co.uk> 2010-12-30 08:11:43 PST --- After applying commit 15056d2c06862627ead868e035fcacc59dce1b1a Author: Chris Wilson <ch...@chris-wilson.co.uk> Date: Tue Dec 21 17:04:23 2010 +0000 drm/i915: Flush pending writes on i830/i845 after updating GTT There is an erratum on these two chipsets that causes the wrong PTE entries to be invalidate after updating the GTT and when used from the BLT engine. The workaround is to flush any pending writes before those PTEs are used by the BLT. Signed-off-by: Chris Wilson <ch...@chris-wilson.co.uk> this reduces to the general i8xx incoherency, bug 27187. For which I have a patch which appears to work on my i845; passing both the wtf test and Daniel's cache-coherency checker!
