[John Kim <johnkim.ubuntu@xxxxxxxxx>]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. The issue that you reported is one that should be
reproducible with the live environment of the Desktop ISO of the
development release - Trusty Tahr. It would help us greatly if you could
test with it so we can work on getting it fixed in the next release of
Ubuntu. You can find out more about the development release at
http://www.ubuntu.com/testing/ . Thanks again and we appreciate your
help.

Title:
  Bridge only working on second netcard - be2net

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This is reduced bug report for a bug similar to:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1213887

  What we have done is to make a simple network and basic installation
  af 14.04 daily build from 2014-03-03.

  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. The connection to 10.230.92.26 i running without problems all the time.

  We get some messages in syslog vlan280: received packet on p5p1 with
  own address as source address

  
  If we switch the bridge to the second networkcard the bridge works:
  # The loopback network interface
  auto lo
  iface lo inet loopback

  # The primary network interface
  auto p5p2
  iface p5p2 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 p5p2
        bridge_maxwait 0
        bridge_fd 0
        bridge stp_off

  
  auto p5p1
  iface p5p1 inet static
        mtu 9000
        address 10.230.92.26
        network 10.230.92.0
        netmask 255.255.255.0
        post-up ifconfig p5p1 txqueuelen 10000

  A normal network setup does not give any problems at all on p5p1
