Hi Roy, thanks for your quick response. First thing, I'd like to ask you to attach the output of "lspci -vvv" and "dmidecode" in this LP so we can validate the adapters and be sure they are exactly the same, and also the motherboard type. Run both commands as root user.
After that, i'll ask you to reproduce the issue and attach the output of "dmesg" command right after reproduction. If you can also elaborate more about the test you're running, I'd really be glad. I'll then provide you custom commands to use the kernel trace system to infer more about the issue. One final thing: are you willing to test with mainline kernel in order to check if there's some upstream fix for your instance of the issue? If so, you can get it here: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable This PPA provides a build from kernel 4.18.
