I'm on a very recent linux kernel and the backend has an Intel PCIe NIC,
which uses the kernel e1000e driver. If it was a cheesy Realtek NIC, I'd
probably worry about that, but I'm not too worried about the Intel NIC on a
pretty recent kernel :)

This is a brand new HD Homerun Prime, so unless it's a bad power supply out
of the box?

That's interesting, I may apply that patch manually and recompile to see if
I can generate stats that may help me troubleshoot, thanks.
