I am currently using drm-tip with your patch applied and my system hangs a couple seconds while booting and when switching modes but I did not experience any hard hangs or crashes as I did with kernel 4.8. I still have this line im my dmesg though: [drm:drm_atomic_helper_commit_cleanup_done [drm_kms_helper]] *ERROR* [CRTC:34:pipe B] flip_done timed out Is this what you mean by WARNING?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
