--- Comment #3 from Jason Ekstrand <jason at jlekstrand.net> ---
I just pushed a band-aid patch that doesn't actually solve the problem but does
get it back to working as well as it did before:

commit 41af9b2e517dd0c17e519490ca915b96f6898390

    HACK: Don't re-configure L3$ in render stages pre-BDW

    This fixes a "regression" on Haswell and prior caused by merging the gen7
    and gen8 flush_state functions.  Haswell should still work just fine if
    you're on a 4.4 kernel, but we really should make it detect the command
    parser version and do something intelligent.
