David, the versions you are using appear to predate Broadwell by some significant time: xserver-xorg-video-intel-2.21.15 - released Aug 21 2013 linux-3.2.0 - released Jan 4 2012 Andrew, you also appear to be using the 2.21.15 version of the Intel driver. The "unknown symbols" mean there is something wrong with your kernel/modules build.</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>
