--- Comment #9 from Topi Pohjolainen <topi.pohjolainen at intel.com> ---
While the failing tests themself don't create RGB32F surfaces to back
renderbuffers (in which case they would probably fail as i965 marks RGB32F as
non-renderable), the surfaces nonetheless end up as render targets. As the
titles of all the failing tests say, tests copy two images. Image copies in
turn are implemented in i965 using blorp (_mesa_CopyImageSubData() ->
brw_blorp_copy_miptrees()) which ends up using RGB32F as GPU render target.

With respect to PRM, isl does the right thing and chooses X-tiling with valign
of 2. This for some reason, however, fails. Old miptree used contrary to the
spec Y-tiling with valign of 2 which for some reason works (at least in these
tests).
Also as mentioned a few comments earlier, for some reason at least
rgb32f_rgb32f.cubemap_to_cubemap works if one uses X-tiling and valign of 4
(which also is against the spec).
