I've double checked the kernel to see if there is a loop hole, again to no avail. So I'm a little bit lost to see where the missed synchronisation is coming from, and I haven't yet thought of a good test to force/catch an error. In the meantime, I've applied one minor tweak to xf86-video-intel.git, commit 60ec35b8d25ecfabf1744ea7bc81109d7f2a90e2 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Tue Mar 5 11:14:37 2013 +0000 sna: Be explicit when checking for an idle bo after CPU synchronisation Do you mind giving that a quick test?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
