At first, it was only really noticeable on BDW because there we weren't disabling eDRAM which is a very large cache and so the amount of data missing was substantial. You could still notice on SKL+ but it was much more minor. With modifiers, however, the result is now massive corruption. I've got a patch for the bug which no one has felt like reviewing.</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> </ul> </body> </html>
