(The DDX does, but it uses local definitions to isolate itself from random versions of the kernel headers.) I would suggest that it is a timing issue - as far as I can tell it requires reusing the wrong buffer at the wrong time to trigger. I've gone ahead and pushed the patch the patch to disable MOCS for staging upload buffers.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
