--- Comment #10 from Stanislav Lisovskiy <stanislav.lisovskiy at intel.com> ---
I got it reproduced on my ICL as well.

It hanged both times, timing out intel_dp_aux_xfer. The log is full of those 
dp aux channel related error messages. Then it just hangs..

I would try updating BIOS, to see if there is any difference.
