I am sure the commit in question is not the cause. I prematurely added the code for the new ioctl and disabled it later on, because my kernel code the commit
was supposed to interact with wasn't accepted.

The problem when bisecting is that now it tries to call a non-existing ioctl if the DRM minor version is >=12, which makes some tests fail. Could you please
check dmesg to see if that's the case? There should be some error messages from DRM.

I think that some of those piglit failures are caused by the glsl-to-tgsi translator. You can disable glsl-to-tgsi by commenting out:

  functions->LinkShader = st_link_shader;

at the end of src/mesa/state_tracker/st_cb_program.c.

Anyway, sorry, I won't probably help you with this bug anytime soon.
