>Description:
Utilizing the MSI P1-102A2M 1u server with two integrated Gigabit ports (1 x Intel 82541 and 1 x Intel 82547) only allows one port to be in use at a time. If both ports are utilized the system will hangup and force a rise in CPU percent. The system becomes almost instantly unavailable over the network.
Utilizing either em0 or em1 individually works without error.

>How-To-Repeat:
Cable both network ports and bring both interfaces to up status.
