Title:
Ethernet no link lights after reboot (Intel i225-v 2.5G)
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Focal:
Fix Committed
Bug description:
I've found that on stock focal the ethernet device on my ASUS ROG
Strix B550-F wifi motherboard gets no link lights after rebooting. I
am able to cold boot it with the network cable unplugged and then the
ethernet works as expected after re-plugging the ethernet.
Workaround:
I have installed the latest mainline kernel from
https://github.com/pimlie/ubuntu-mainline-kernel.sh which appears to solve the
issue. (vmlinuz-5.9.3-050903-generic)
This issue looks similar although I wasn't able to find the firmware for my
motherboard so I didn't try the solution:

I found here that I could cold boot and it would work:
