On Linux 4.18 I can't reproduce this on Skylake anymore (after months of testing). I can't test on Broadwell as my machine didn't lived as long as this bug. I don't know which exact commits fixed this issue on Skylake and why it doesn't work on Broadwell as other people reported. BTW: on Linux 4.19rc1-3 iommu is broken again for graphics but this is unrelated issue which is being worked on.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
