<pre>Well, I think this may be the problem:
[drm:i915_gem_object_create_stolen_for_preallocated [i915]] failed to allocate
stolen space
If I comment out "if (ifbdev->vma)", like said in <a class="bz_bug_link

title="NEW - [CFL] black screen with DP MST"
href="show_bug.cgi?id=104158#c28">bug 104158, comment 28</a>, and
recompile the kernel, it will be about 50-50 chance for tablet to boot up
normally, with image on screen, backlight regulation and video acceleration (it
plays 1080p video from youtube).
Also I can't boot up with "drm.debug=0x1e log_buf_len=4M" (always black
screen), and it won't reboot or power off with this kernel (spams with "failed
to unmount /oldroot/*" and hangs on "kvm: exiting hardware virtualization",
maybe my fault somewhere)
(And, well, is anybody here? It was about two month without any updates)</pre>
