2bf4db1697a02cd58062e0ebac086fda72f29945 is the first bad commit
commit 2bf4db1697a02cd58062e0ebac086fda72f29945

    meta: Don't use fixed-function to decompress array textures

    Array textures can't be used with fixed-function, so don't.  Instead,
    just drop the decompress request on the floor.  This is no worse than
    what was done previously because generating the GL error (in
    _mesa_set_enable) broke everything anyway.

    A later patch will get GL_TEXTURE_2D_ARRAY targets working.
