Hello all,

While testing the 5.4rc1 release, i noticed my Ethernet never coming fully up, seemingly having a timeout problem. While bisecting this i landed at the commit dee23594d587386e9fda76732aa5f5a487709510 ("e1000e: Make speed detection on hotplugging cable more reliable") as the first bad commit. And indeed just reverting the commit on top of 5.4rc1 resolves the problem. Let me know if you have further questions, or patches to test!
Is runtime PM enabled (i.e. "power/control" = auto)?

Yes it is set to auto.
Is something like TLP or `powertop --auto-tune` is in use?

Do you still see the issue when "power/control" keeps at "on"?

With "power/control" set to "on" it does still cycle between up and down. But yes i have upower and powerdevil running. After killing them the connection comes up with "power/control" set to "on", yet not with "auto".




Also please attach full dmesg, thanks!
