I disable mine because I'm running it in qemu and the virtual machine apparently has a flaky mpbios. The virtual network cards it presents never receive the DHCP response from the virtual DHCP server with it turned on, and I get watchdog time out errors. Disabling it makes those go away. But again, that's on a virtual machine and not a production environment. Maybe someone else can speak to the wisdom of enabling/disabling it for your scenario. Stefan Johnson
