Ok. Atm, I'm without much ideas what can cause this, I'll try to reproduce it on my Haswell here. One more thing, is i915 built-in or module for you? We end up with a different resume sequence in the two cases, so trying if you can reproduce the bug with both ways could be useful.</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>
