This is definitely suspect and very strange. Chris mentioned DMC and power context corruption as potential culprits in this area. It seems to be turning out into something which could use a 1:1 session with a BXT or GLK to hunt it down locally.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
