I still think this is totally valid and correct.
When you turn auto-neg off the link partner is going to react to that, it might drop the link. After a while, the link partner will give up trying to perform auto-neg and might fall back to 10/Half. At which point, the link might allow traffic flow. However, in this example, you have a duplex mis-match, so it might not work correctly.
Turning off auto-neg is something you need to do at both ends, and you need to then force both ends to the same settings. Link down is expected. I would actually be suppressed if no link down events were reported.
