--- Comment #10 from Chris Wilson <chris at chris-wilson.co.uk> ---
[  2548.122] kgem_create_2d(1366x22, bpp=32, tiling=1, exact=1, inactive=0,
cpu-mapping=0, gtt-mapping=0, scanout?=0, prime?=0, temp?=0)
[  2548.122] kgem_surface_size: tile_width=512, tile_height=8 => aligned
pitch=5632, height=24
[  2548.125] kgem_set_tiling: handle=42, tiling=1 [1], pitch=4096 [5632]: 1

Wait a sec. That's not the error path, that's the success path. The kernel
returned a pitch less than we requested. On no.
