Thank you both for your replies, I'll try to find the thread mentioning the pcie_aspm and see that it was for. I am using 7.2, and I have installed Intel's latest driver. Unfortunately, it did not resolve the issue. Also, just as a note, it happens much more frequently when the NIC is receiving a heavy amount of traffic. The very odd thing is again that it only happens with the second nic, not the first.
