Unexpected Event 8400 ff000180
This will occur only on boot, will only occur with Solaris 10, and only on newer firmware (9.6.x).
This error only occurs when the system is attached to a screen via USB regardless of what the input-device variable is.
Updating the OS to S11 will clear the issue as well, as it's not present in S11 installs on the same systems due to how S11 handles OBP USB code.
