--- Comment #52 from Shmerl <shtetldik at gmail.com> ---
I tried this workaround:

    for plane in pri cur spr; do echo 20 500 500 500 500 500 500 500 >
i915_${plane}_wm_latency ; done

But it's causing problems in my setup, (daisy chained monitor becomes unstable,
and flickers).

I had to revert to previous values:

    for plane in pri cur spr; do echo 2 19 28 32 63 77 83 99 >
i915_${plane}_wm_latency ; done
