I found one possibly relevant difference: Non-Working state: dev.igb.0.link_irq: 0 Working state: dev.igb.0.link_irq: 2 Seems to be reproducable. If I power up the machine and load if_igb for the first time, dev.igb.0.link_irq is always "0" and after unloading and loading again, it's always "2". And tcpdump only captures anything when dev.igb.0.link_irq=2. That's also true for reboot. When I don't power off the machine, just rebooting, packets are passing right from the first kldload!!!
