Just a small update:
I have been using i915.enable_psr=0 i915.enable_dc=0 i915.enable_fbc=0 i915.enable_dp_mst=1 parameters for a few days, but except the very first or first two days when I unplugged the docking station, it doesn't helped at all.
So I decided to add error_capture=1 (record the GPU state following a hang) and a few days later complete it with a manual/udev disable for the i915 rc6. The kernel parameter has been removed (https://bugzilla.redhat.com/show_bug.cgi?id=1573482), however the function is still in the driver (/sys/class/drm/card0/power/rc6_enable:1).
