I haven't seen any hang in fbo-d24s8.  fbo-blit-d24s8 hang is now fixed in:

    i965: Tell the shader compiler when we expect depth writes for gen6.
    
    This fixes hangs in some Z-writes-in-shaders tests, though other
    pieces don't come out correctly.
    
    Bug #30392: hang in fbo-fblit-d24s8. (still fails with bad color drawn
    to some targets)

Both fbo-blit-d24s8 and fbo-d24s8 don't make system hang,now. Verified the bug.
