Frustratingly, this seems to have now resolved itself, so I can't test the patch. All I did was leave the machine off for a few hours and turn it back on - then it was working again.
I now can't reproduce the problem, with or without the Lan Boot ROM option. The PHY ID now reports as 0x001cc912. I'll come back to it later and see if it breaks again. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/1876593 Title: Ethernet not working/Realtek RTL8169 fails to load Status in linux-signed package in Ubuntu: New Bug description: With the latest kernels on Ubuntu 20.04 LTS, my onboard Ethernet has stopped working.
