1) The system boots incorrectly on the 3.13 kernels. The USB keyboard is not 
working, neither is the Ethernet connection.
The systems boots correctly on 3.14-rc+ kernels, so also on 3.15 it works ok.
This is a separate issue, which I can setup as a separate bug.

With 14.04.1 around the corner (which is running a 3.15 kernel) I rather
make it work with that one (but that is my personal choice, I understand
that). The reason is the deployment contains a huge amount of these
servers and for 1 month I better can focus on 3.15 timing wise.

So let's focus on the other part, where this bug report IS for.

2) The firmware provided by Ubuntu is older than the one from HP. Ubuntu 
4.0.590, HP 4.0.593.
The system loads the firmware from the NC375T flash at boot and reports an 
error.
That firmware is also added to this bug as an attachment.

With this firmware from the card loaded at boot by the system, the card
works. I tested that personally on multiple (exactly the same) systems.
The main issue is that the firmware included in the mainline kernel is
not up to date enough.

Hope I explained it more clearly and correctly else please shout.
