Hello Joshua Miller:
I have anecdotally heard of other people having problems with the Intel
X710 card on Ubuntu 14.04. The default kernel is 3.13, and it seems to have
inadequate or non-existent driver support. You mention that you've upgraded
the kernel to 3.19, which is quite recent. I'm not sure what the driver
status is in that kernel, but on your results, it sounds like there are
still problems. Have you tried using drivers from the Intel website (see
the link below)?
