Comment 20 for bug 997978

here it is. already posted it above with ip's xx:

================================
auto lo
iface lo inet loopback

# device: eth0
auto eth0
iface eth0 inet static
  address 176.9.126.79
  broadcast 176.9.126.95
  netmask 255.255.255.192
  gateway 176.9.126.65

# default route to access subnet
up route add -net 176.9.126.64 netmask 255.255.255.192 gw 176.9.126.65 eth0

auto br0
iface br0 inet static
  address 176.9.126.79
  netmask 255.255.255.255
  gateway 176.9.126.65
  pointopoint 176.9.126.65
  bridge_ports eth0
  bridge_stp off
  bridge_fd 0
  bridge_maxwait 0
  up route add -host 176.9.126.92 dev br0
  up route add -host 176.9.126.93 dev br0

======================================
and brctl show
======================================
bridge name bridge id STP enabled interfaces
br0 8000.c86000e94a2e no eth0
                              vnet0
virbr0 8000.000000000000 yes
======================================

I also did an mtr during downtimes and it shows that packages are lost on dom0 -> .79
I still hope it is some kind of misconfig, but as said before same network/bridge config runn without interupts in ubuntu 10.4 lts.
Thanks for your patience.
