Comment 48 for bug 349314

@Steve -- this patch was applied and a kernel released, there were then reports of almost immediate hangs on an X61 thinkpad with Intel graphics (bug #364545), and there were also reports of general compiz hangs occuring on intel hardware (https://bugs.freedesktop.org/show_bug.cgi?id=20520). A kernel with just this patch was produced and was shown to fix the X61 issues and thought to fix the general issues as seen on the upstream bug.

In parallel discussions with the patch author indicated that the patch had not been accepted as is upstream and we should expect a revised patch for this issue. As yet we have not seen the updated patch.
