olad seems to interfere with the Zbox to Beta UART/Serial console interface baud rate:

[root@beta ~]# stty -F /dev/ttyPS0
speed 115200 baud; line = 0;

axiom-zbox:~# service olad start

[root@beta ~]# stty -F /dev/ttyPS0
speed 38400 baud; line = 0;

it would be a good idea to restrict 'olad' to specific devices, either via udev or via configuration
