Strightforward git bisect tells that e6b0b6a82f9c93fe3dd060ae54719456474a74a3 is the first bad commit. But it's merge commit which merges v3.5-rc7 into drm-next. None of it's parents has this problem. So, I've rebased all these patches from drm-next to v3.5-rc7 and bisected among them. And the winner is b4ae3f22d238617ca11610b29fde16cf8c0bc6e0 (drm/i915: load boot context at driver init time) which refers to <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - [SNB, HSW, IVB, VLV] make sure MBC boot is enabled" href="show_bug.cgi?id=50237">https://bugs.freedesktop.org/show_bug.cgi?id=50237</a> Seems like there is no public documentation about this stuff so I have no idea what the hell is happening here. I've reverted that commit from 3.9.9 and it works like a charm. After that my automatic script unable to reproduce this problem.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
