Odds are that I downgraded to a previously working ddx and it still does not
work. Only a very long version works.

Where to find xtrace?

I updated a kernel too. From 3.11.2 to 3.11.3. Any ideas:

Daniel Vetter (3):
      drm/i915: fix hpd work vs. flush_work in the pageflip code deadlock
      drm/i915: fix gpu hang vs. flip stall deadlocks
      drm/i915: fix wait_for_pending_flips vs gpu hang deadlock

Jani Nikula (2):
      drm/i915: try not to lose backlight CBLV precision
      drm/i915: do not update cursor in crtc mode set

Ville Syrjälä (1):
      drm/i915: Don't enable the cursor on a disable pipe
