--- Comment #9 from Paulo Zanoni <przanoni at gmail.com> ---
First 4kb of stolen memory being used? Aka possible regression from commit
011f22eb545a35f972036bb6a245c95c2e7e15a0.

At drivers/gpu/drm/i915/i915_gem_stolen.c, function i915_gem_init_stolen(), at
the very end, on the drm_mm_init() call, can you please change the second
argument from 0 to 4096? Also please in the stolen_usable_size argument right
above this, subtract 4096 to compensate that. Then please test this and report
if the problem still happens.
