--- Comment #19 from Alex Deucher <alexdeucher at gmail.com> ---
Certain panels can be really picky about sequencing or delays in the link
training.  I suspect there are mainly just slight differences in the
programming sequences that some panels just don't like.  The core link training
code for DAL is here:
