Hi It seems like my issues are caused by faulty hardware. The activity LEDs on the port do not light up even when I'm in the BIOS menu, and there's also no activity when I try to NIC boot.
I didn't really consider the possibility of a hardware failure since it happened to coincide with the upgrade to Fedora 28. Luckily the Latitude E6420 has a separate I/O board that can be swapped out, but it remains to be seen if that's where the fault is. In any case, I've ordered the part to give it a try. I greatly appreciate the time and patience devoted to helping me resolve my issue.
