I am getting a page fault with a new install of FreeBSD 5.3 Release. Something changed with the nge driver in FreeBSD 5.3. I did not have this problem with 5.2.1. I just performed a clean install on a box that had been running 5.2.1 RELEASE for a few months. The box is an Instrusion Detection System. I have fiber taps in place on the network and use the rx ports of the nic to monitor the traffic. In 5.2.1, i would do this to bond ports and monitor them: # ifconfig nge0 media 1000baseSX mediaopt full-duplex promisc -arp up # ifconfig nge1 media 1000baseSX mediaopt full-duplex promisc -arp up # ngctl mkpeer fec dummy fec # ngctl msg fec0: add_iface '"nge0"' # ngctl msg fec0: add_iface '"nge1"' # ngctl msg fec0: set_mode_inet # ifconfig fec0 promisc -arp up However, when i set the media options for nge0, the machine panics and dies. The panic message is hand typed below. FreeBSD 5.3 RELEASE.
