From the second resume onwards, the bug appears at least at every resume. Please see attached dmesg log with drm.debug=0xe - the bug trace starts at 4274. I have a Lenovo T400 with GM45 and I'm connecting it to an external monitor via a docking bay and disabling the LVDS screen. I've tried using xrandr to disconnect the external monitor and connect the internal screen but the bug appears to happen anyway. This happens with 3.14.14 and 3.15.9. It did not happen with the 3.13 series kernels. Let me know if you need more information.</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>
