Hello.
I have 3 Raspberries 4B, running 24/7 a main application, on Raspberry Pi OS 5.15.32-v7l+. This application executes a "reboot" command each day at 4:00. It has been working without issue for months, but some days ago, the reboot hanged on the 3 Raspberries, after the reboot execution, at the same time. All we could notice was this message in the screen of the 3 devices, repeated several times:
"unregister_netdevice: waiting for eth0 to become free. Usage count = 2"After that, it was necessary a power cycle, and then they seem to work normally again.
They are all in the same remote location connected to Internet through the Ethernet interface (they are sharing the same switch). I acces to them using ssh, from a laptop connected to internet over a tunnel created from the Raspberry to a server with public IP with command "autossh".
I hope that someone could help me to identify possible causes os this issue so I could prevent it from happening again.
