<pre>This issue could also manifest if link training is being attempted before the
USB-C Hub is ready to accept a signal. A small delay before attempting Link
Training with a USB-C LSPCON may work.
Ricardo,
Could you try adding a short delay msleep (200) to the start of
intel_dp_start_link_train() and see if your retries drops to 0?</pre>
