I have updated the armbian kernel from version 20.11.3 to version 20.11.6 and eth0 only works by forcing the switch to 100FD. If I leave it on automatic, the port negotiates at 1000FD but loses most packets.
Any suggestion?

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

Yes, sorry:

Thanks. Nothing fancy from a quick look. As a temporary fix you can use armbian-config to revert to an older kernel, perhaps the version you were using before if it is still available and then freeze firmware updates.

Thanks, it is a new installation, I had the problem of the disabled hdmi port.

When I saw today's update, I installed it and everything just got worse. I have tried the buster and bullseye images with the same result. I will try to prove.

cubietruck seems not to be affected as well so there might not be a general issue with A20 SoC but with this particular board

Downgraded to version 5.8.16 and everything seems to work fine for me, hdmi & eth0, then i freeze firmware updates. (Sorry for my google english)

no worries

Hi,

I had the same effect - eth0 only worked by forcing the switch to 100FD after upgrading to 5.10.4 from 5.9.14. If I leave it on automatic, the port negotiates at 1000FD but loses most packets.

No connection possible with a TP Link Switch.

It seemed to be a little more stable connecting to a Fritzbox - I could login using ssh after connecting the Pi to that.

After forcing the Fritzbox to 100FD I could login using SSH and downgrade to 5.9.14 (which I had before).

5.9.14 confirmed to be stable for ETH0. For HDMI I don't know.

Hope that helps.

This worked, the port negotiates fine in autoconfig at 1000FD with no packet loss.

Great! Is this fix part of the 20.11.7 builds and current armbian repositories kernel / dtb packages?

I bought an SD Card to test which should arrive tomorrow and want to know if I need to compile my own kernel package or if it is supposed work "out of the box" with current repositories...

 

Sorry if this is a dumb question but I am not familiar with github and build cycles and stuff - also happy to learn how I could determine this by myself...

 

Many thanks!

I think it should.

Those hotfixes are triggered manually so there is no relation on github. Regular way:
