FreeNAS loses network connectivity

[Visseroth]

So I've setup a FreeNAS server for a friend and he doesn't have direct internet access but can get his server online though his hotspot as needed.
Anyhow, he uses it for just file storage but has been having issues with it losing network connectivity.
Previously it was having issues restarting at random. I troubleshot it and was unable to duplicate the problem and even managed to transfer about 4TBs of data to and from the server without error.
My first thought was that it was a dirty power supply as I could slightly hear one of the power supplies making noise, so we've since pulled it out but are now having issues where the network interface just stops.
Currently it has a Intel NIC in it (em0) vs the onboard NICs. The onboard is currently disabled via hardware (bge0 and bge1)

Motherboard is a X8DTH-i
Dual Quad Core Xeon E5540 with 48GB of RAM.
Build FreeNAS-9.10.2-U1 (86c7ef5)

Here is what I saw in the log after restart on the gui interface...
And attached is the debug.

Have you tried to reinstall FreeNAS? Replace the Ethernet cable, Have a direct connection between FreeNAS and a computer (no switch, router, anything, just a single Ethernet cable)?
