Since commit 767f70df (from !7720 (merged)), the fail these piglits onn Zink + ANV:
depthstencil-default_fb-blit samples=2
depthstencil-default_fb-blit samples=4
Here's an example:
$ piglit/bin/fbo-depthstencil blit default_fb -samples=2 -auto
[...]
Testing default_fb.
Testing glBlitFramebuffer(depthstencil).
