remote DoS actually

openSUSE 11.4, kernel 2.6.37.6-0.7-xen dom0

/etc/sysconfig/network/ifcfg-bond0:

BOOTPROTO='static'
BONDING_MASTER='yes'
BONDING_SLAVE_0='eth0'
BONDING_SLAVE_1='eth1'
BONDING_MODULE_OPTS='mode=balance-xor miimon=100'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR=''
MTU=''
NAME=''
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'

/etc/sysconfig/network/ifcfg-br0:

BOOTPROTO='static'
BRIDGE='yes'
BRIDGE_FORWARDDELAY='0'
BRIDGE_PORTS='bond0'
BRIDGE_STP='off'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='192.168.x.y/z'
MTU=''
NAME=''
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
USERCONTROL='no'

some domUs running with virtual NICs attached to br0

vif=[ 'mac=00:16:3e:aa:bb:cc,bridge=br0', ]

ping -R any-domU-running-on-192.168.x.y from remote machine causes dom0 crash
(at least network subsystem, unfortunately remote console is not available on
that host)

any ideas ?
