Looks like this device has newer sequence version which the current parser is not identifying. You can use intel-gpu-tools to dump the whole VBT. There is also a DSI sequence parser in igt which can dump the sequence block. Can you attach the two dumps. Also can you try the patches which are currently under review in intel-gfx for version 3 sequence to see if it fixes the problem - <a href="http://lists.freedesktop.org/archives/intel-gfx/2015-July/072463.html">http://lists.freedesktop.org/archives/intel-gfx/2015-July/072463.html</a></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>
