Hi,
I was able to recreate the issue on a board here. The ifplugd service, which is used to detect ethernet connectivity status, is bringing eth0 up as soon as you bring it down. You need to stop the ifplugd service before bringing et... Daniel Vincelette

Good find. Interestingly in the 6.6 kernel both the AM62A and AM62P have those lpm-disable options for both USB0 and USB1.

Hello,
We noticed that the message is different for success and failure.
It is only coming from a few laptops.

I've attached a schematic, nothing special.

Hello,
It might be that you need to take br0 down before taking eth0 down. The issue could be that br0 isn't allowing eth0 to go down.

The schematic I received was only the ethernet section so its missing the USB. Jonathan Cormier

I have not been able to reproduce it here, yet.
Do you get any messages from "dmesg" when the communication is dropped?
If you unplug and replug the cable, does the connection re-establish?
Have you sent Jonathan a copy of your ... Michael Williamson
