Unfortunately those patches still have a few issues (regressions) left, so I don't like to backport them to stable kernels for now. Relevant patches are commit 24a1f16de97c4cf0029d9acd04be06db32208726 Author: Mika Kuoppala <<a href="mailto:mika.kuoppala@linux.intel.com">mika.kuoppala@linux.intel.com</a>> Date: Fri Feb 8 16:35:37 2013 +0200 drm/i915: disable shared panel fitter for pipe and commit 9d6d9f19e8146fa24903cb561e204a22232740e3 Author: Mika Kuoppala <<a href="mailto:mika.kuoppala@linux.intel.com">mika.kuoppala@linux.intel.com</a>> Date: Fri Feb 8 16:35:38 2013 +0200 drm/i915: clean up panel fitter handling in lvds If those two indeed fix things for you, we could backport them once the regression they introduce is tackled. If those aren't the fixes, a reverse bisect to hunt for the first good commit would be interesting.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
