--- Comment #21 from Clinton Taylor <clinton.a.taylor at intel.com> ---
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?
