Auto-negotiation is and will probably remain a major pain.

I work in network operations at a large, high-end computer show every
year. We typically have over 100 network drops, most at 1 Gb/s or higher
and multiple OC-192s (10 Bb/s SONET) to the outside world.

Every year when the drops are connected, a number don't work. The
problems are ALMOST always auto-negotiation. This is new,
state-of-the-art equipment from major vendors of both switches and
routers. The problem does not seem to be getting worse, but it is not
really improving, either. The problems are NOT close to the majority,
but they are far from rare.
