However, I do not think that the matter is in port availability. I also try to set the priority of the irq/120-eth0 interrupt. This one also works only from the web interface and does not work after reboot. I try four ways:
irq\/120-eth0
irq/120-eth0
120-eth0
eth0
All four work only from the web-interface and do not work after rebooting.
