Auto negotiating console speed could cause sonic to lock on a wrong speed under rare conditions. The only way to come out of the wrong speed is to issue line break or restart console service with forced speed, or reboot sonic. Lock down the console speed to avoid these situations.

- What I did
Auto negotiating console speed could cause sonic to lock on a wrong
speed under rare conditions. The only way to come out of the wrong
speed is to issue line break or restart console service with forced
speed, or reboot sonic.
Lock down the console speed to avoid these situations.
- How to verify it
Boot up and check console service is using fixed baud rate.
Passed continuous reboot test.
