--- Comment #19 from Jani Saarinen <jani.saarinen at intel.com> ---
Hi, Just this week there some was fix made. I actually have same NUC7i7BNH and
with that both Thunderbolt dock and from that to DP-MST monitor => that to
normar just worked now. Also now I have Lenovo MST HUB connected to monitor and
that also works now. Can you try now with latest drm-tip and exactly fix that
Laksmi informed: https://bugs.freedesktop.org/show_bug.cgi?id=112212 however
that was also regression. 

But can you still try with latest-drm-tip as that now works for me too. 
Can you also attach /sys/kernel/debug/dri/0/i915_dp_mst_info
