The bug usually bites on cold boot, and not on reboot. I tested 20 cold boots and hit the <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED DUPLICATE - fontconfig eat all my memory" href="show_bug.cgi?id=19">bug 19</a> times. Reverting that commit does convincingly avoid the problem, tested another 20 cold boots, 0 failures. I added some printk's to trace the logic in intel_crtc_disable_planes() and intel_commit_primary_plane(). There is no obvious behavioural difference in the case of reboot (working) vs cold boot (no display).</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>
