Thanks for result of the 5.4.0-75. Now the range can be narrowed down. The strange thing is there's no r8169 related modification between 74 to 75. So it's not that easy to identify which commit commit the problem. I build a modified 74 version to help. Can you try the kernel in https://people.canonical.com/~mschiu77/lp1938697/74_118/? Thanks

It appears that support for the second ethernet port on my Lenovo m90n-1 has been dropped or isn't working as expected. After upgrading to 5.4.0-80-generic my second ethernet port Both ethernet ports use the r8169 driver. If I switch back to the previous kernel 5.4.0-74-generic. The second ethernet port is usable again. I did attempt under 5.4.0-80-generic to see if I could get an error message. When the driver attempts to discover the second ethernet port the following error is thrown. "unknown chip XID fcf" Support output below: --- Before update.
