The problem seems to appear randomly on my SKL-Y so you probably just got unlucky. I think this is related to a bug in the hw readout code (could be same as <a class="bz_bug_link bz_status_NEW " title="NEW - [HSW] *ERROR* crtc 21: Can't calculate constants, dotclock = 0!" href="show_bug.cgi?id=91428">https://bugs.freedesktop.org/show_bug.cgi?id=91428</a>) or the DP link training issue you're seeing in the dmesg. Both issues are causing quite a lot of igt fails on SKL. I'll look into this tomorrow since it seems quite urgent.</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>
