[Intel-gfx] i915 (ivy bridge) + 4.10.3 + gimp = BUG in list_move_tail()

[Jérôme Carretero]

Hi,


After a kernel update from v4.9.10 to v4.10.3, any time I bring out the gimp,
the i915 driver NULL-pointer dereferences something in list_move_tail(),
somewhere in i915_gem_evict_for_vma().

I'm providing the kernel log, if more is needed (say you aren't
aware of this regression) I'm available.

xf-86-video-intel is 860c3664fe79c1fe92095ff345068f1fc7e4e651,
mesa is 11.2.1, xorg-server is 1.19.2, but I don't think it matters.


Regards,
