On the 20 unit pool we only are able to run release-candidate images, so drm-tip is not stable enough to be appropriate. On the 20 units, we will begin testing with kernel 4.12 (yocto rocko 2.4.2) and ensure the bxt i915 firmwares are loaded to see if the problem goes away. What is the official intel-gfx position on enable_rc6=0 and/or max_cstate=1 ? Should we be using these if the goal is maximum stability? Are there any particular commits in drm-tip that could explain this issue that we should consider backporting into 4.10 or 4.12?</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>
