mmmhhh... how did you get it? I tested it on drm-tip kernel
(different versions), mainline kernel (different versions) and
Tvrtko's kernel and didn't get any failure.

All the patches were applied on latest igt until this one (to
make sure I didn't forget any dependency with future patches).

I executed it in loop several times and I have other tests on
top, I might have forgotten something.

Thanks for testing it,
Andi
