<pre>OK, I had a short look into this,
So it seems that we have that,
amdgpu_atombios_dp_aux_transfer() calls amdgpu_atombios_dp_process_aux_chan()
which has either a ucReplyStatus == 2 or 3 from atombios returned.
If you could please attach dmesg logs after running
# echo 0xf > /sys/module/drm/parameters/debug
and waiting for the situation to reoccur that would be most useful.</pre>
