The error is also in 12.04 and later kernels. If we use the first network card a a bridge: /etc/network/interfaces: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto p5p1 iface p5p1 inet manual auto vlan280 iface vlan280 inet static address 10.230.80.26 netmask 255.255.255.0 gateway 10.230.80.1 dns-search 10.230.80.11 10.230.80.12 bridge_ports p5p1 bridge_maxwait 0 bridge_fd 0 bridge stp_off auto p5p2 iface p5p2 inet static mtu 9000 address 10.230.92.26 network 10.230.92.0 netmask 255.255.255.0 post-up ifconfig p5p2 txqueuelen 10000 You begin to lose pings and the connection to 10.230.80.26 becomes very unstable.
