Thank you for your bug report. It does look like rather an hardware/driver/kernel issue than a network-manager one though, reassigning

To obtain a DHCP IP in Linux on the PC, I must either fully shutdown Windows then cold boot into Linux, or manually reset the ethernet adapter with echo 1 > /sys/bus/pci/devices/0000:00:19.0/reset The connection then comes good. I can see various DHCPDISCOVER and network-related traffic in journalctl -f during the time the machine is attempting to set an address on the interface, periodically the "activation of network connection failed" error message displays. Other discussion online suggests setting a spoofed, different MAC on the interface I am using Ubuntu 19 and Mint Cinnamon 19.1 to test and can reproduce this over multiple boots. It has apparently been a longstanding bug, perhaps due to how Windows is setting some aspect of the ethernet controller for a WOL or other boot-related operation. Either way, it's entirely confusing. Perhaps resetting the adapter should occur if this situation arises, particularly in LiveUSB/LiveCD scenarios.
