Skylake has been out for 7 months and we still have problems Ok, I looked into that bug and it seems its not the same. It specifically mentions external monitors and also not black screen flickering, but more a graphical flickering, without the completely black frames in between. Nevertheless, I tried the proposes patches from <a class="bz_bug_link bz_status_NEEDINFO " title="NEEDINFO - [bdw edp] Screen Flickering" href="show_bug.cgi?id=91393#c102">https://bugs.freedesktop.org/show_bug.cgi?id=91393#c102</a> on intel-drm-nightly and I still got the FIFO underrun ERROR and also the black screen flickering. So thats not a solution. Also, it seems that the FIFO error does appear for the first flicker, but not for any ones after the first, so in my opinion, it can be used as an error criteria. I could bisect the kernel further, but as seen in <a href="https://bugs.freedesktop.org/attachment.cgi?id=123104">https://bugs.freedesktop.org/attachment.cgi?id=123104</a> there are so many commits, which I cannot build. Maybe someone can help me to compile one of these? I can then do the remaining (since they are all in order, it seems like the reason they dont compile might be the same).</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> </ul> </body> </html>
