Hi,

I`m runnig a Proymox Backup Servas as a VM in PVE enviroment. The PS always looses LAN connection from time to time. Everytime when the VM looses connection the System log of the PVE shoes the message:

Jun 05 14:50:31 NAB6 kernel: fwbr203i0: port 1(fwln203i0) entered blocking state

it's been reported that it's a kernel bug, I'm rebuilding a vm for that reason, I might try to go back a kernel or a version
