Good news: no more crash Bad news: as soon as I give an IP adress to the interface, the link is down (the link led on the switch is light off) When I boot the computer, the led on the switch is on. When I kldload if_bfe, the led is still on. When I dhclient or ifconfig bfe0 the NIC to give it an adress, the led is off and I have the message: Interrupt storm detected on "irq18: bfe0 uhci2"; throttling interrupt source. One step in the good direction anyway! Thanks Phil.
