<pre>The problem is
<7>[ 10.069905] [drm:intel_bios_port_aux_ch [i915]] using AUX B for port C
(VBT)
which is impossible. Port C is a TypeC port and can only be connected to an AUX
starting from AUX C (and the AUX depending on the corresponding DP-Alt/TBT
power well).
In addition either the rework for legacy-DP functionality is missing from the
RVP or the BIOS setup is not configured accordingly.
So this is again a VBT issue wrt. the port C information in it. Please assign
to someone who could generate a new VBT, removing the port C info from there
completely, or fixing the AUX info in it (if the fi-icl-dsi has indeed the
required DP rework).</pre>
