For completeness, I should add that the upstream fix introduces another bug which may cause some corruption. This one is fixed in this commit:
commit dc3bfebcf77d943b7e8495d30d0ee3d01b3042a5 Author: Chris Wilson <ch...@chris-wilson.co.uk> Date: Thu Dec 30 18:02:21 2010 +0000 drm/i915: Don't skip ring flushes if only invalidating Commit 15056d2 tried to optimize away a flush if there were no outstanding writes on a ring (in order to prevent a too-early-flush during ring init). However, this has the unfortunate side-effect of eliminating the texture cache invalidation, and so causing rendering artefacts.
